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 this circuit likes low gain transistors in the rectifier. The LM394CH is a high gain … Read more

Super Fuzz Build!

Build your own Super Fuzz! The Super Fuzz is an octave fuzz used by Pete Townsend, Muddy Honey, J. Mascis and others. Read this post to learn more about the Super Fuzz.

Univox Super Fuzz

Super Fuzz is a circuit that has many variations. It’s one of the popular building blocks that has been used for decades. It’s built around a full wave rectifier that produces an octave fuzz sound. similar circuits that use the full wave rectifier: Super Fuzz Kay Fuzztone Univox Super Fuzz Honey Psychedelic Machine Third Man … Read more

Super-Fuzz V2

I updated the Super-Fuzz Board to fix a problem with the last version. The prototyping service at PCBWay.com is very inexpensive, which facilitates my workflow.  The schematic I used for this project came from Freestompboxes.org. It’s based on the original with a couple mods. The Tone switch has been turned into a pot to provide a range … Read more

Fuzz Face Ge NPN

This is an NPN Germanium Fuzz Face. I designed the PCB in Eagle, and had the PCBs made at OSHPark.com. The original Fuzz Face used germanium PNP transistors. The germanium transistors is supposed to have some special mojo. PNP types are more common but require either a battery charge pump to create a reversed power … Read more

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 https://shop.pedalparts.co.uk/product/bassblendmuff. It worked well but the board doesn’t have an LED! So the wiring is a little … Read more
