The Peachy Fuzz

The Peach Fuzz clone
This one is a little off my main path (or the king's highway) towards the ultimate fuzz. The PeachFuzz is one of those new boutique, over-the-top fuzz boxes which you see by the hundreds. Actually, some of the best pedals you can get today are made by little boutique companies which have an enormous amount of pedals or at least update their catalog quite often. Because a lot of them are hand made or partly hand made they can change their designs quite fast and have a new pedal on the market every month, be it a modern clone of a classic fuzz, a newly designed fuzz, vintage overdrives, delays, you name it. To pay some tribute to these great manufacturers, here's a short and partial list of boutique pedal brands:
D*A*M , Analog.Man, Keeley Electronics, El Nano, Frantone, Skreddy Pedals, Wampler, Catalinbread, Devi Ever, ZVex, Fulltone, Love Pedals, Way Huge and the list goes on and on.

All these boutique brands sell top quality, great sounding pedals and they all have some unique designs which make them stand out. Some focus on their own designs while others focus on getting that vintage tone of the great legends of the past. Luckily you can't start a pedal company without having a killer fuzz box on the shelf, so the number of fuzz circuits and variants grew over the past few years from dozens to hundreds, hence...the fuzz explosion, or as I call it, fuzz-plosion.

One company that had some great designs but went out of business is Frantone and for a long time I have been looking at their offerings and always wanted to build a "Cream Puff" clone which sounded very interesting to me. As my want-to-build list just got longer I forgot about it for a while until I stumbled upon an article which ranked the best 50 distortion, overdrive and fuzz pedals of all times. Needless to say, every pedal I have ever built or wanted to build was there: Big Muff Pi, Tube Screamer, Fuzz Face, Tone Bender, Klon Centaur, Maestro Fuzz Tone, Pro-Co Rat, Range Master, Tycobrahe Octavia, Hot Cake, Fuzz Factory, Boss BD2, you name it. Wow....what a list....you should really check it out, I have building noise boxes for a while now and I can safely say that the most important pedals in rock history are definitely there:

Going over the list it turns out that the Frantone PeachFuzz, which I've never heard of before, reached number 47! very nice. Had to listen to it a few times on Youtube before I set my mind on building one. I figured it's kinda like a Big Muff style of sound, but the Schematic looked different and I thought I maybe I can learn something new. Took me a long time to get around to it, and decide on the layout and version to choose from.

The Frantone Peach Fuzz. Entered the top 50! all-time distortion pedals 
Well, for the good things: It's a fuzz, it's tight and focused and it sounds like a good mid gain BMP clone...but......, it's just not that much of a fun-to-play with pedal. It has limited versatility with it's best with the FUZZ knob over half, and working the TONE knob can get you some Big Muff Pi op-amp style from the 70's. Not bad. But that's it. I figured it might be good to get some wicked sounds putting the fuzz in front of a real Muff or an overdrive so I decided to keep it and box it. After pairing it with some amp-like overdrive pedals I can say that I finally got it to sound good, focused and interesting.

Blue knobs, blue LED, blue texts and peachy gradients
Yellow faced and Blue "fonted" as on the original, Blue "knobed", blue LEDed and turned vertically for smaller rig footprint. I used the original circuit so there was no real way to change the name of the pedal. I just had to add some "peachy" texture so I painted the enclosure to give it more peach gradients.

Over the past few years I have tried a lot of circuits which didn't get boxed and remained naked in a drawer. This one got boxed because it's just a good sounding fuzz. It behaves well in a band setup and it gives great chords and solos.

So, the verified layout can be found on the Tagboardeffects blog:

The schematic I used is given here: http://i50.tinypic.com/1zc1eg4.jpg

The fact that this pedal is extinct by now makes it a better collector's DIY item and I think that recently I have grown more and more fond of its thunder.

FuzzBoxGirl's youtube video was removed for some reason so I added this video as there aren't many other PeachFuzz videos on the web anymore: 


And if you can handle the power of this pedal, just listen below. I played a single coils tele through the PeachFuzz clone on a HiWatt 70's emulation amp. Listen to the various settings and then with a ROG Thor just behind the fuzz. Some of the riffs are also played with a treble booster in front of the PeachFuzz. This baby really roars. Take care, rock on!

The Fluffy Fuzz Cake

The Big Muff Pi (~3.14) was the first major fuzz pedal by the NY based company - Electro-Harmonix (EHX). The legend says that the first units were brought in 1969 to Manny's Music Store on 48th Street, NY, and a week or so later Hendrix picked one up. The circuit was aimed to recreate some of the fuzz tones conceived by Hendrix using a more complicated design than that of most fuzzes from those days. It was supposed to do everything the FuzzFace did with some extra features and a nicer sustain.

Over the years, a lot of Big Muff variants appeared, each with it's own characteristics and subtleties. Some due to part changes by EHX and some by the fact the the company went out of business and other manufacturers issued they're own versions. Gilmour switched from the Silicon FuzzFace to a BigMuff Pi somewhere around 1977. All the solo guitar work on Animals and The Wall incorporates a Big Muff. Santana also used this unit during the mid 70's. During the late 80's and early 90's the vintage Big Muffs and other variants, most notably the Russian Sovtek version, were a big part of the grungy alternative sound of the bands which defined the genre like Sonic Youth, Smashing Pumpkins and Nirvana. Mudhoney went as far as naming their Ep "Superfuzz Bigmuff". Having so much legacy and history around this pedal, I had to try it but I couldn't decide which version to go for. It was actually the first fuzz pedal that was named a distortion pedal.

The original circuit I built was taken from the GeneralGuitarGadgets site shown here. Some of the changes made by EHX over the years as well as the designs made by other manufacturers can be found on the same website here. Although they rely on the idea of cascaded gain stages with diode clipping on each stage, they all sound a little different (tonestack, caps, trannies etc.).

The most gratifying unit I built around the Big Muff concept was the ROG 22/7. The ROG team did it again with a super cool design to get the entire pie in one bite. The name comes from the number pi, but the sound is the fluffy triangular pie which we love so much (How did EHX ever get a way with such a nasty name for a pedal?). The most notable thing about the pedal is that it is based around a CD4049UB IC which makes up the gain stages, and the fact that you have 3 variants in a single circuit!!! the original classic sound, the flatter Russian Sovtek sound and the scooped Ram's Head version. What a great pedal. Every guitarist I played with loved it. It's sustain is super smooth and you can get a very heavy Billy Corgan/Thurston Moore sound easily. Very very cool. The circuit can be found here. A lot of info on this pedal can be found on the Pistones website.


I admit that I did not intend to dwelve so deep into Big Muff territory when I first started my quest for the ultimate fuzz, but this is a great versatile fuzz unit and could easily satisfy grunge heads and fuzz heads alike.
