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 The site is no longer active, but it has been archived in a few places; here is…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…
Super Frequency
This is my spin on Tim Escobedo’s Ugly Face. The original is a great DIY project anyone that hasn’t built it should give it a try. Super fun, unique sound, parts are easy to get, and it’s not a difficult…
Bigger Muff part 2
Looking at the Bigger Muff. Still not happy with this, it doesn’t sound bad it’s just that the range of the controls is unsatisfying. There are plenty of usable sounds some but some of the settings are not useful. Here…
