Mother Fuzz revisited
Awhile back I built the Big Muff Plus by Mic Tester, over at FreeStompBoxes.org. This is a Big Muff with a JFET input and output buffer, and a James tone stack, which offers Bass and Treble controls, for a wider…

ETI Hyper Fuzz on the scope
I broke out the synthesizer and ran a sine wave into the ETI Hyper Fuzz, and examined the output on the Mordax Data. I think the fuzz tone is good the scope view is not super exciting, looks like a…
Univox Super Fuzz
This is a clone of the Univox Super Fuzz. I built a few of these here. This one uses a matched transistor pair: LM394CH. I thought this would enhance the octave effect since matched transistors enhance this effect. Seems like…
Fuzz Face NPN Ge
I have this bag of NPN Germanium transistors. These are rare and you don’t see them much in pedals. They offer a huge advantage over the typical PNP types found in Fuzz Face’s, you can use a regular power supply!…
Super Fuzz v2
This is a second version of the Univox Super Fuzz. Check out the first version in these posts. The first version fit a 1590BB sized box. This time I thought I’d try and get it into a smaller 1590B box…
PWM by Tim Escobedo
I wonder what happened to Tim Escobedo? The author of Circuit Snippets, a page with a lot of great ideas for guitar effects. The site is no longer active, but it has been archived in a few places; here is…
Pedal Building Workshop at Noisebridge: Fuzz Face
The next pedal building workshop at Noisebridge will be about building a Fuzz Face. If you’re in the bay Area check out the workshop on meetup! the Fuzz Face is a classic fuzz circuit with a bit of magic. its…
Summon Fuzz
I built this a few years ago. I got it out and played it for a while. sounds pretty good. This is a Big Muffin with a diode lift switch, and a blend control. The PCB is from It…
Deformis: Ugly Face with Mix mod
This is my take on Tim Escobedo’s Ugly Face. I replaced the LM386 with a dual op-amp and and added a mix control. The LM386 is a great chip but its gain is limited to 200. A single op-amp can…
Another Super Fuzz!
Another Super Fuzz build. I used the first PCB I designed from a post over at FreeStompBoxes.org, read about that first build here. This one looked good but it didn’t work! I put it aside because the problem wasn’t obvious.…
Retro Channel: The Fuzz Clone
The Fuzz by Retro Channel is a Fuzz circuit built around the CA3046 transistor array. It’s a lot like a Fuzz Face and Tone Bender. It makes use of all of the transistors on the CA3046 and sounds pretty good…
Deformis – Ugly Face with a mix control
Here is an updated post with a schematic and parts for the Deformis. This started as Tim Escobedo’s Ugly Face. I made a few changes. I swapped the LM386 with a dual op-amp. The 386 was used in the Ugly…
