Gristleizer

Gristleizer The Gristleizer is a circuit by Roy Gwinn dated back in 1975 and combines a tremolo with an oscillator-controlled filter. The most famous user was probably Chris Carter from Throbbing Gristle. It has a considerable versatility, allowing you to achieve sounds from polite, smooth tremolo and auto-filter wah wah sounds, to industrial grinding distortion,… Read More

Katzenkőnigin

Katzenkőnigin Catalinbread’s Katzenkőnig combines elements of a Tone Bender MkII fuzz with a Rat distortion to create something that sings like a fuzz but is tight like a distortion. It has a wide range of response that covers from a beautiful singing tone, to tight, harmonically-rich crunch, all the way to fuzz mayhem. It took… Read More

Casper Electronics Echo Bender

Casper Electronics Echo Bender The Echo Bender is a mix of multi FX pedal and noise maker that can process external signals or create complex sounds on its own, from warm analog sounding echo, to highly adjustable distortion, ring mod style feedback or noise generator. These modes can be used on their own or it… Read More

Ugly Face

Ugly Face Ugly Face is a completely all-out fuzz unit for fat, noisy buzzsaw sounds that has become a DIY classic. Originally created by Tim Escobedo on his Circuit Snippets web page, it’s a relatively easy build with very few components and a really cool spacey/sci-fi sound. I used this layout (minus the Threshold pot) but… Read More

Arrows

Arrows This one-knob pedal is a clone from EarthQuaker Devices analog pre amp boost. Very few components and a cool pedal to have around. Follow this step by step video if you want to build it. Read More

Dirrrty Delay

Dirrrty Delay Extremely lo-fi and nasty delay pedal, based on a modified pt2399 delay board. The addition of delay time and feedback control to the existing circuit pushes the chip into wild oscillation territory, allowing the pedal to function as a standalone noise instrument as well. It is an easy mod with very few components,… Read More

Noise Generator + clean blend

Noise Generator + clean blend A simple pedal that can be used as a standalone noise generator or to mix white noise into your signal chain. It has Volume, Blend and Filter controls and it's based on this Synth Nerd blog post. Read More

Comodoro Fuzz

Comodoro Fuzz This fuzz pedal was made at the Mutan Monkey Instruments Pedal Attack workshop out of a kit provided by Comodoro. Read More

ISD1820 Filteroid

ISD1820 Filteroid Mainly used as a sampler/looper, the ISD1820 chip is used here in feedthrough mode. This turns this circuit from Synthlurk into an audio processor that can be used as a filter, amplifier, fuzz, suboscillator, noise generator or distortion unit. Check this thread on LMNC Discourse group to learn more about it. Read More
