Fuzz Faces : What's the deal?

See our FAQ for the history of the fuzz face.

Disclaimer: A fuzz face is not an easy pedal to get a great sound out of! If you have a Cort guitar and a Crate amp, don't expect to sound like Jimi with a fuzzface. You will have to have an excellent guitar and amp, have played for at least several years, and used some other fuzz pedals to appreciate the sound and feel of our Sun Face or modified Fuzz Faces.

Why does a fuzzface need a mod to sound good?

Unlike a pedal like a Tube Screamer, which will always sound good if the right chip and other parts are installed correctly, a fuzzface is a very finicky circuit. The transistors used in a fuzzface make all the difference in tone, feel, and amount of fuzz/cleanliness. Germanium transistors were the first type of transistors generally available, starting in the early 1960s. They are not very stable or easy to manufacture consistently. Since silicon transistors took over from germanium, almost nobody makes germaniums anymore, and the few that are made just don't do the trick in a fuzzface circuit. Each transistor used in a fuzzface needs to be tested for several parameters including gain, leakage, noise, and tone to make a great sounding fuzz. These transistors are just not available in any decent quantity. For these reasons, no big company can, or usually even tries to, make a classic germanium fuzzface that sounds good. It's too much of a hassle.

We can build our SUNFACE pedal for you, or modify your existing Fuzz Face, either a Dunlop reissue or Arbiter UK reissues to makes them sound GREAT, just like Clapton in Cream or early Hendrix. The sound is nice and smooth, singing bluesy tone, not harsh noisy fuzz.

These pedals are VERY SENSITIVE to your guitar volume : if you turn down a Strat's volume to about 7, there is very little distortion. At 9, it is a nice smooth bluesy tone, like Clapton in Cream. At 10, it is quite fuzzy, especially if you have hot pickups or humbuckers. Also, if you use another effect before the fuzz face, it can make it get a nastier distortion. You may try running a Distortion or compressor into the fuzz face, or vice versa, with varying volume settings on the guitar and/or effects. But for the purest tone, there should be no effects between the guitar and the fuzz. However, effects with true bypass that are turned OFF are OK before the fuzz (for example, a Teese wah). Vintage style wah pedals have some issues when used with a vintage style fuzz face (though Jimi did not seem to mind!). To cure that, the Foxrox Wah Retrofit is available. The Z Vex Wah Probe seems to work fine with our sunface, for a cool alternative.

All fuzz faces (and our sunface) have true bypass, so we don't need to modify them for true bypass.

Analog Man Sun Face

We are now making these in our own cases, as the Analog Man Sun Face . They are built in small gold boxes or we can use a 1970s MXR paperweight boxes, with our own SUNFACE circuit board which was made small enough to fit in almost any enclosure. As you can see, this is a VERY high quality board the same type as used on our other pedals. It is better quality than any other fuzzface clone you will find, with shielding, plated through-holes, etc to meet military specs. It also has an internal CLEAN trim pot which you can see on the top left. This trim pot acts just like turning down the VOLUME knob on your guitar, to clean up the fuzz. It can be used to preset the sound if you prefer the sound with the volume knob rolled back a bit. It can also be used to kill Radio Frequency Interference, which may be a problem on high gain pedals in some areas, by turning it down a hair. like all our handmade pedals, the Sunface has true bypass, so when off they do not alter your sound at all.

Transistor Testing

On the left is some of our test equipment we use for testing out transistors for our Sun Face and Sun Face MK-II pedals. These are ugly but perfect for testing the transistors for four parameters which are critical for the best sounding fuzz

New Old Stock NKT-275 transistors!

In July, 2002 we started offering a NOS NKT-275 version of the Sun Face, using New Old Stock British Newmarket 1960s NKT-275 transistors. These are the actual ones used in the original $expensive germanium fuzzfaces, not the skinny US made copies used in the new fuzzfaces since the 1990s (which look and sound totally different). You can take a peek into one of our NKT-loaded pedals on the left. It also includes an additional BIAS trim pot inside to set the exact bias on these transistors, for the ultimate sound. The Blue trim pot is for Bias, which should not need adjustment often, while the big White one is the CLEAN (input adjustment) knob. The BIAS pot really helps if you play at different temperatures. You can turn it down a bit at higher temperatures, and up a bit at lower temperatures, to keep the transistors happy and sounding best at their SWEET SPOT which is about 5 volts. The Sunface manual has more information on adjusting this.

The sound of these NKT275 transistors is quite similar to the other types of germanium transistors that we use. But the NKT275s have a bit less fuzz, and less high end fizziness. They have a deeper tone and clean up better. If you turn down the volume on your guitar, the NKT275 sound will be totally, sparkly clean without any fuzz remnants. Our NKT275 transistors are not high gain, that is why they clean up so well and are so smooth sounding. However we do have some high gain NKTs we have sorted out over the years, with the same basic awesome sound but fuzzier, with more high end, but without the ability to get totally clean.

We sold out our first batch of NKT-275 transistors in just a few months, but found more. These early 1970s "new" NKT275s are the same size but don't look exactly the same. They have a bit more gain, less (almost no!) leakage current, and sound a little less dark, with better high end definition. They are from a military supplier in the UK and were tested to a NATO spec. They are not the USA reproduction NKTs used in the new fuzzfaces or in some other fuzzface clones. When I retested them here, 95% of them worked perfectly unlike the last batch which was about 25% dead. I find these to be the best quality, best sounding germanium transistors I have ever seen, we have used them in our Beano Boost also. The SUNFACE reviewed by Guitar Player magazine had the old NKTs, while the one reviewed by TONEQUEST magazine had the newer ones.

These are now available for the same $50 NKT optional price as before, though they cost me 3 times as much to buy. We are still using these "new" NKT275 transistors now. We also have some of the "old" NKTs that we will need to use as we are running low on the newer type. If you want the older ones (not as clean or clear sounding, lower gain, but a cool smoky, bluesy tone) just put a note on the order form "old nkts please".

If you want the NKT sound, but with more fuzz, and a bit brighter, with a reasonable amount of cleanup like other fuzzface clones and our generic germaniums (not 100% clean), we have some HIGH GAIN NKTs that we have saved over the years. They are the same parts, they just tested out higher in gain than the ones we normally use. We can install these in your sunface or fuzzface mod for the same price as the normal NKTS - just put a note "HIGH GAIN NKTS" on your mod form or you can choose them as an option on buyanalogman.com.

We also have some really cool 1960s Japanese 2SB transistors that we are using for our standard germanium (non NKT) Sunfaces. These are a little brighter and fuzzier than the NKTs, and cannot get totally clean. I remember buying Acetone organs back in the early 90s to get these transistors for making Fuzzfaces when I friend told me how great they sounded. Now I found a batch of NOS 2SBs so we can use them for a while, we have about 50 pairs for 2008.

AC128 transistors?

You will read on some websites that some original fuzzface pedals used an AC128 transistor. However, I and all my fuzzface guru friends have never seen these in an original fuzzface from the 1960s, and we have seen literally hundreds of them. The AC128 was however found in the grey reissues made in recent years. The AC-128s we pulled out of these reissue fuzzes sound horrible. We also tried all the AC-128s versions available on ebay and from suppliers all over the world but none sounded good. We really hoped we could find an alternate transistor (as we are getting low on the NKTs) but we could not use any of the AC-128 transistors so we do not offer them as an option.

Silicon fuzz

We have some BC108 and BC183L silicon transistors, and have been making silicon Sunfaces for a few years now by request. The BC108 are in small metal cans while the BC183 are plastic. Silicon fuzzfaces came out in about 1969. They are fuzzier than the germaniums, and brighter. The silicon transistors have much higher gain. They don't get totally clean by turning the guitar down like the NKTs but they do clean up quite a bit and are sensitive to your dynamics. Check out the sound sample below to hear this.

We can make these for the same price as the standard germanium version. The sundial is not really needed as the silicon transistors are not temperature sensitive. But you can use the sundial knob to dial in different sounds if desired. We do put the BIAS trimpot on the inside of the two-knob sunfaces so you can still tweek it if desired.

Silicon fuzzfaces are negative ground, so you can use a power supply without fear of melting it down. But it will still sound better with an old style battery. The FUZZ knob on the silicon version usually sounds and works best if you turn it down a little bit (on the germanium I usually like it up full).

On the order form it says BC108 but if you want the BC183 just make a note. They are about the same sound, really. I think Eric Johnson has BC183 in the red fuzzface he has used for years. We also have some BC182 which are awesome in combination with the BC183, easy to make a perfect matched pair that way.

I got four old 1960s Fuzzfaces in for repairs and tweeking in early 2008 from a collector. Two were BC108 silicon so I compared them to a BC108 Sunface that I just finished. I was very happy when I found the sounds were almost identical except the sunface was a little clearer sounding. The other two old fuzzfaces were NKT275, one was decent but the other was really dull and woofy. Our NKT sunface was better than both but he wanted to keep them original so we left the original weak transistors in them.

Sun Dial

We now put the SUN DIAL on the Sunface to make a 3 knob small gold pedal. The middle knob is on center of the Sun Face Graphics. It is the exact same function and circuit as the internal BIAS trim pot on the 2 knob model. It is used for keeping the fuzz happy at different temperatures, and with different or worn batteries. We call it the SUN DIAL and the knob is painted to match the pedal! It is a $25 option (free with NKTS on the small gold box only, for the time being!). We factory set the SUNDIAL so the face is vertical at our shop temperature (70 degrees or so depending on if it's Winter or Summer!). You can set it by ear, just turn it up until the buzziness goes away as much as you like. Jim Weider has an NKT Sunface with the SUN DIAL and likes to run the sundial higher than our normal setting, he turns it almost all the way up for less fuzz and a purer tone. You can turn it down all the way for a sound like "spirit in the sky", where the fuzz fizzes out.

Box styles and sizes

Up till August 2007 we used our "small" box for most Sunfaces as seen on the left, the Sunface with Top Jacks. These are 2.5" wide, 4.75" tall, and about 1.5" high. It is the same box used for the Mini Chorus, Mini Bicomp, Beano, etc. Starting in late August 2007 we are using our SMALLER box for most Sunface pedals, as seen on the pedal with side jacks on the left. These are 2.25" wide, 4.25" tall, and about 1.25" high, the same size as old MXR pedals or our MXR paperweight box. I like these better as they are lower profile and leave more room on the pedalboards for more pedals!!

We are still using the old style boxes for the TOP JACKS option or when an LED is ordered. The top jacks helps with real estate problems on some boards. These can only be built in the old style "small" box as there is no room on the newer "smaller" box for top jacks or an LED.

Here is Jon Butcher playing his NKT sunface with a Nash Strat with .010 strings, into a Reinhardt 18 head with a THD 2x12" cabinet, recorded with a Shure 57 mic. Fuzz knob was about 3:00, sundial about 1:00 and volume about 12:00. Sea Of Blues Enjoy!

Here are some clips by Rogers Stevens of Blind Melon from their 2007 album. He is playing his Nash Strat with Rio Grande pickups through our Sunface NKT into a Blockhead amp.

Greg V. former Double Trouble, Buddy Miles guitarist got an NKT Sun Face in Sept 04 and wrote
I love this pedal, VERY fat and feels good to play. I love how dynamic this pedal responds to the changing attack of my fingers. Greg made a clip of it, recorded at a medium-loud living room volume with his Black Fender Tele with Nocaster pickup > No pick-fingers only > Sun Face > '66 Ampeg Gemini 1 > SM57 > Akai DPS24 recorder. No EQ and just a bit of reverb. GregV_SunFace_Jam1.mp3

There are some NKT Sunface samples from Robert Morency on the Unkle Groove myspace page . He used a stock strat and a deluxe for these Hendrix and Trower tones. He also posted some cool clips on youtube : Strat , Strat Clean , with the Sunface used as a booster and Les Paul.

Here are some BASS GUITAR samples

Here are some samples of Jim Weider's fuzzface sound, from his 2002 CD "REMEDY". This is with our standard germanium Sun Face. The song is called Metal Jam. Note that you can still hear the guitar clearly, it's not a fuzzed-out sound. Of course you can get a much fuzzier sound by cranking the FUZZ knob and the volume knob on your guitar, and if your amp is distorting. But this is the basic tone I am striving for with my fuzzes, one that a pro player can use to tailor his sound without losing his signature tone. Jim used both Fender and Marshall amps mixed together for this tone. He has since upgraded his sunface with our NKT275 transistors which he likes even better.

Here is a video of Sid McGinnis at a studio playing his sunface through his new Tweed Twin amp. The sunface has the fuzz knob up all the way, he uses the guitar to change from SPARKLY clean to pure fuzz. The avi video is dark and audio is poor (built in mic in a canon camera, not even a real video camera) and it's huge, about 8MB. But if you want to check it out, here is sidsunface.avi .

Here are some samples from Diego Andrea. He gets AWESOME tones from his historic Gibson guitars and uses our Sunface and Beano Boost almost all the time. If you like classic 60s British and American blues check this guy out. Electric Days, Diego Andrea go to the bottom and there should be some sunface clips after his songs. He used an SG into a blockhead 50W Plexi head. The songs before the Sunface samples all use the Beano Boost.

Here is a cool video demo of the silicon BC108 sunface, from a good customer.

Here is some excellent info on Jimi Hendrix's pedals on the emplive.com web site. You can hear the difference when Jimi turned on his fuzzface on one of the clips.

Sun Face Options

Power Supply Problems

We do not like to add a power jack to these pedals, as they are a compromise with a fuzz. The germanium versions (NKT) are reverse polarity, so sharing a power source with another pedal will blow out the power source. It blows because the negative ground on normal pedals flows through the patch cord shield to the positive ground of the fuzzface, shorting out the power supply. Positive 9V in the fuzzface is connected to ground through your patch cords. Here is an article about the problems of using power jacks on reverse polarity pedals from Andreas in Sweden. Using a single power cable from the Voodoo Labs Pedalpower 2 would be safe though.

We do not require using a reverse polarity plug on any of our pedals. Use normal center negative boss type power supply wiring. We change the polarity inside the pedal so you don't have to.

A power jack may add AC hum noise, and a power supply can affect the tone, as the best sound is obtained by using an old style non-alkaline battery. I get these two for a dollar at the DOLLAR STORES. I like the Maxell or Panasonics. An Alkaline battery will sound a bit dull in a germanium fuzzface, it can lose some character (you can hear the difference in a sound sample above). It's not just the voltage that makes batteries and power supplies sound different. It's the resistance, inductance, and capacitance in the battery, which is part of the circuit in a fuzzface.

A power jack can also cause oscillation (squealing) on some high gain sunfaces with some power supplies. The gigrig virtual battery should solve oscillation problems, along with isolating the power supply so you can use any power supply with our positive ground pedals. The VIRTUAL BATTERY also solves ground loop problems which occur when you use a daisy chain or the same power with more than one pedal. We will soon offer the Virtual Battery as an accessory and sunface option on our website. Here is more info on the GigRig Virtual Battery

LED option

Some people want an LED added. An LED will not affect tone at all, but may cause some popping when switched ON, and will drain the battery about four times faster. Without an LED, the battery will last at least a few hundred hours of use, so don't scrimp on the tone and you won't be wasting money on batteries anyway. The sunface uses under 1 milliamp (1mA) of current when you are playing, and almost no current if you stop playing or turn it off. So if you play with the fuzz on for 2 or 3 hours a night, a cheap battery will last at least 100 nights! If you use your fuzz in a pedalboard and it's a pain to unplug the input jack to disconnect the battery, we can install a BATTERY ON/OFF SWITCH. This is built into the FUZZ pot, when you turn it down all the way it clicks and kills the battery. It is a $15 option. The options we have now are transistor type, Sun Dial knob, jack placement, power jack, and on/off pot.

Here is a way to test the battery without having to open the pedal.

Here is a chart I made up that shows how the battery drains over time. Battery Drain Chart The battery used was a cheap heavy-duty (non alkaline) battery from the dollar store. An alkaline would last MUCH longer. It looks like the battery is fine for about 8 days or so. After 16 days, it will still work but then goes downhill FAST!

CC2 NKT fuzzcard

We can now offer these transistors for the Captain Coconut-2, in our NKT fuzzcard. These are only available direct from analog man. The cards are $95, or $50 extra if bought at the same time as a new CC2. See our CC2 page for ordering information.

Artists and Reviews

David Gilmour got two more of our Sunface Pedals for his ON AN ISLAND tour in 2006. The bass player, Guy Pratt, was using the BC108 silicon on his bass. Here is more info and pictures .

Jon Butcher sent me such an amazing email about his sunface that I put it on it's own page. Also see his sound sample above.

Doyle Bramhall II used our Sunface NKT with sundial on tour with Eric Clapton starting in 2004. He also had our Bicomp on his pedalboard and had been using our TS9/808. On the left is a screen capture from rehearsal.com where you can see some awesome video interviews and hear him playing the Sunface. You can see the Sunface NKT with sundial in the middle of the board. Here is another shot of his HUGE PEDALBOARD with the Sunface in the middle and Bicomp a few pedals to it's left.

Michael Katon, from Hell, Michigan, is constantly touring Europe playing Detroit blues/rock and boogie. He has been using old fuzzfaces for years with his Marshall Plexis and old Fender Super Reverbs. Michael loved his first Sun Face so much that he ordered another one in case something happened to his first one. Then he had one changed to the NKTs. He wrote me in late 2002:
I had a chance to use the NKT the other Nite through two 100watt Marshall half stacks...I think I sterilized most men in the club and ended up having to sign a few bare breasts (girls of course)...so it's definately doing a good job for me!!!!!!!!

A few months later he wrote me :

On his next tour after more time with the sunface he wrote :

Here is a sound clip from his cd Bad Machine featuring the sunface.

Scott Henderson got an NKT275 Sunface with sundial in late 2003, I hope to hear it on his new CDs!
Greg Martin from the Kentucky Headhunters also has a modified Analog Man Arbiter Fuzzface, we changed it over to our NKT-275 transistors for him.

Sid McGinnis got one in early 2005 and is having a blast with it. He used it at the Rock and Roll Hall of Fame induction and you should be able to hear it nearly every night when he's playing it on the David Letterman show. Sid wrote me: Sunface has been tremendous at the show. Level at 11:00, Drive full or just under, and Sunface at 3:00 or less if I really want FUZZ. Effect on all the time (even on Al Green tune). It's Jimi, Cream, and American Woman in a box!!

Corky James used one of our modified Dunlop Fuzzfaces on Avril Lavigne's hit album. Jasin Todd of the heavy rock band Shinedown is using an NKT sunface live and will try it on their next Atlantic record. Andrew Carillo is using one with Joan Osborne on tour starting in 2005. Dan Auerbach of The Black Keys is using an NKT sunface. Rontrose Heathman from the Supersuckers said he is a huge fan of his NKT-275 sunface and runs his comprossor and KoT Ver2 beside it.

Steve Mac from The Australian Pink Floyd Show got a BC108 silicon sunface in late 2006. If you ever get a chance to see these guys it's well worth it! He emailed me:

Doug Rappoport of the Edgar Winter Band got one in early 2006 and emailed me :

I got it today. Plugged it in... YEAHHHH BABY! WOOHOO! That's it my brothu! That's what I've been looking for! You da man, Mike. Thank you so much. And thanks for the shirt. Its great too!
All the best, Doug.

Ordering

We normally build these in the small gold box, it is professionally powder coated and baked on. These pedals take a long time to build so they usually take a few weeks to build. The NKT Sun Face with sundial $235, that is what most people order. The standard germanium or] BC108 are $185 plus options.

Please use the new website for ordering these as it allows adding any options, accessories, and online status and tracking capabilities.

Use buyanalogman.com for ordering.

4/2001 Arbiter England Made in UK fuzz faces modified!

The new UK made Arbiter Fuzz face is in a nice case, looks great, and seems well made but they just don't sound right. Some seem to make almost no sound at all! Well We have modified dozens now and know just what needs to be done. We had a few dozen new grey Arbiter fuzz faces that we tuned with our transistors and parts to make them sound just like the late 60s Germanium fuzz faces. These get our entire classic germanium mod, we change all the transistors and resistors on the boards and caps if needed. Available for $215. 2/02 SORRY SOLD OUT but we can still mod yours!!!!! One of these Arbiters I modified went for $255 on ebay, item 860031524

Custom Modified Sun Face

We do not normally sell this custom pedal but this will give you an idea of what we can do if you are crazy enough...

This 4 knob sunface was made for Guns n' Roses. Curtis Laur, who is working with them, wanted the knobs on the fuzz so he could document the settings and the guitarists could leave the guitars' knobs up all the way. The two standard knobs are on the left - Volume and Fuzz. The third knob is the same as the standard internal trim pot on the sunface - the input trimmer. It works the same as turning down the VOL knob on your guitar, to CLEAN up the sound. So we labelled it C for Clean. The forth knob is a TONE knob but with a twist. There is a mini-toggle switch below the TONE knob. In the UP position, it acts like the TONE knob on your guitar. But if the fuzz is up high, your TONE knob does not do much. So we added the DOWN position which puts the tone circuit AFTER the fuzz for a more pronounced roll off of high end. But since simple is better and sometimes you don't need to roll off the tone, we also have a MIDDLE position which totally bypasses the tone control. You may remember the old 1970s Big Muffs which had a TONE BYPASS switch on the back, a very good idea.

This pedal is not as good as the normal Sunface NKT with sundial for a player, as you should use the knobs on your guitars for more control. It was built so the guitar tech could do the adjustments. So we don't normally build these, also very expensive as each knob and switch is a $25 option.

On the right is a custom-painted fuzzface I built for Tele-man Jim Weider of the Jim Weider Band (and The Band). It looks too cool if I do say so myself... Sorry I don't have any more like this, when I try to make another one the paint always comes out terrible. Kenny Wayne Shepherd now has this one, I made another one for Jim in an old 1970s red fuzzface housing. Jim has since had me re-box it in one of my grey COMPROSSOR boxes so it does not look like any other fuzzface. It was in effect the first SUN FACE pedal. I later put the NKT transistors and the SUN DIAL knob on it for Jim and put it in the small gold box.

Here are some old updates since we started this page

Update 7/97 :

The Dunlop Fuzz Face (Dallas arbiter) reissue was not good sounding when it came out in '93. They used "Germanium Devices co." reproduction NKT-275 transistors with very thin, stuttery sound. But in '97 I saw fuzz faces with different transistors used in the High gain position and they sounded pretty good (still using the NKT in the other position). They were NTE 102A which I USED to use in my mods before I found some great NOS germaniums, but the recent 102A transistors I obtained in the last few years have been terrible. Maybe Dunlop was able to get some good ones made (actually only re-branded) by NTE again and test them. But still some are not very good as it costs too much to test each set of transistors by hand and ear like I do.

Update 7/98 :

Dunlop is back to using two NKT-275s, but they sound pretty decent now. How did they do it? By adding an extra resistor on the back of the board to make the old circuit work well with the lousy new transistors. You can try it yourself if you have a fuzzface with those transistors and no resistor on the back. Solder a 22k resistor (1/2 watt should be fine) on the back of the board at the points where the 33K resistor is soldered in. The 33K is Orange Orange Orange (then silver or gold) and should be in the middle of the board. If you somehow have good transistors this mod will make if worse, but with lousy flatulent sounding transistors it should help a lot. If you dont like it simply cut out the added resistor. I have tried it on a few pedals but it did not help on some at all.

Update 6/00 : The current Dunlop Fuzz Face reissue has the switch mounted to the board, and several changes to the circuit. See below for a picture of the previous version from 1993 - mid 2000. There are two trim pots on the new model, but not in the same part of the circuit where Fulltone and others put them. There is one in place of the 100K resistor that goes between transistor 1 input and transistor 2 (actually a 56K in series with a 100K trim pot, so if you set it half way you get the normal 100K). The other is in place of the 33K resistor going from transistor 1 to zero volts. Again they use a 100K trim pot, in series with a 10K resistor, so you can dial in 33K if desired. There is an added cap to ground on the input. There is an added cap and resistor on the 1st transistor which normally just goes to +9V. There is also an RT-1 (thermistor?) device to ground on the direct connection between the 2 transistors on the signal path. The Fuzz control capacitor on the wiper of the pot is now referenced to 0V instead of 9v. So it is no longer easy to make a new fuzzface into a classic one, but we can do it now. See below for more info.

Update 7/00 : I found more transistors (only 25 out of 200 were useable!) and have them here, so we can do the classic mod for you for $60 plus $5 S & H in the usa. Also the we will install all carbon comp resistors exactly like the original 60s fuzz face. The mod does not include the fancy paint job like Jim Weider's as that is nearly impossible to do. We can do the standard mod only if your pedal does NOT have the switch attached to the circuit board. This picture is the pre-2000 version which we can easily modify :

Update 4/01 : I can also modify the Arbiter England reissues, and had them new in stock for $215 modified!

Update 4/02 : We can also modify the new dunlop pedals, the ones without the MOUTH on the face. These have the circuit board attached to the switch. We can modify these by removing the whole circuit board and installing one of our SUN FACE boards. We use your switch and pots and case. Price is $100, there is a choice for this version on the MOD FORM below. It will look like THIS after the mod.

Update 5/02 : We are using some cool transistors pulled from Farfisa organs for the SUN FACE. We call this version the PATGOD (Piper at the Gates of Dawn) in reverence to Pink Floyd, whose album on which you will hear tons of reverb-drenched Farfisa organs which have nothing at all to do with fuzzfaces... We still have a few of these available.

Update 7/02 : We finally scored some original 1960s NKT-275 transistors from the UK, after a search which took over nine years! We will now be offering these optionally in our mods and Sun Face pedals for an additional charge, while they last. There is also a BIAS trim pot included on the Sun Face with the NKT-275 transistors so you can tune them in perfectly.

Update 8/02 : We can now offer the mods on the "Jimi Hendrix" JH2 model black fuzz face style ROUND pedal. Not the little red square pedal. We will install our SUNFACE board as we do in the new Dunlop Fuzzfaces. We also disconnect the power jack as it has the wrong polarity for a germanium fuzz. Same price as the new style Dunlop Fuzzface mod.

Update 10/02 : We are about out of the NKT transistors, sorry! We have people all over Europe trying to scrounge up more... But we do have several other new old stock transistors available now in good quantities, so we can make a sunface to your tastes (smooth, warm, low gain, high gain, really fuzzy, etc).

Update 11/02 : We have some more NKT transistors that look slightly different but sound even better!

Update 1/03 : We can offer our mod on the ROGER MAYER blue rocket "The Fuzz Face" pedal, using the existing circuit board. We change all the components on the board but 2 capacitors. The FUZZ pot used is a little higher so it can get a little crunchier and more fuzz. We can change that to our standard FUZZ pot for an additional $10. The price for the RM mod is the same as the standard older fuzzface or arbiter fuzzface mods. We can also add our BIAS trim pot on the board of this pedal (standard with NKT option).

Update 10/05 : We have been making silicon sunfaces and mods for a few years, we finally got around to putting the info up on this website. We are using old BC108 transistors which are the best of the old 1970 silicon type, as used in Eric Johnson's old red fuzzface.

Update 6/07 : We got in some really cool sounding NOS Japanese 2SB transistors, we will be using them in our standard (non NKT) Sunfaces and mods. Sold out in late '07 but got some more for '08.

Update 8/07 : We will use a smaller Gold box for the Sunfaces except for the ones with top jacks.

Update 4/08 : We are getting low on the NKTs we have used for the past five years. So we will be offering the older style NKTs optionally for the same price. See above for more info.
