Fuzz
Hornby Skewes Shatterbox
Slightly modernized and improved. The original ran on negative power supply with low gain jellybean PNP silicon transistors with BCE pinout. This layout calls for low gain NPN silicon transistors with CBE pinots so you can easily socket the normal suspects like PN2222, 2N3903 etc. And a trimpot for the biasing the fuzz section replaces … Read more
JOHN HORNSBY SKEWES: Silicon Zonk II
I thought a post was required for the silicon Zonk II, as looking at some schematics online, some appeared to be a little different. Being a pedal from the sixties, variations and tweaks were not uncommon. At the moment, this is probably best known as being the inspiration for the Reeves Zo. This is fun … Read more
Satronik Fuzz Sustainer
A few months ago, Alex and I made an attempt to trace an old polish fuzz/distortion that looked incredibly cool and was supposed to sound in the vein of a Rat or a Big Muff. Soon, we realized that the circuit design was quite unique, not resembling anything else. It is basically a bootstrapped booster … Read more
Parasit Studio Subspace Transmission
Another lovely contribution from Chris Stelloh! This layout VERIFIED by Chris himself so it is good to go. More info about this monster is avaiable HERE.
REEVES ELECTRO: ZO
I saw this on the Gray Bench Electronics youtube channel, and given the cost and apparent popularity of Reeves pedals, I thought I’d post a layout. The schematic is also on screen for a lengthy period of time. In depth explanation provided at Gray Bench, but in short, it’s a silicon two-transistor Zonk II with … Read more
CLAYBRIDGE SOUND SYSTEMS: Fuzzmaster (AKA D*A*M Fuzz Supreme)
I probably should start by saying that this is not a full trace, as I do not have one in my possession. However, you can put a lot together based on photos online. Mainly on the D*A*M forum here and via some reverb listing that show some different angles. The first three stages don’t appear strange, … Read more
SONIC VI: Silicon MKI Tone Bender
The SonicVI silicon MKI Tone Bender is firmly based on the original, with a few additions and some minor changes. Being silicon based, the transistors do not self-bias, so additional resistors have been added from V- to the base of Q1 & Q3. The transistors used are early Mullard PNP silicon OC202 which are quite … Read more
Smallsound / Bigsound Buzzz
Schematic is avaiable HERE. Note thjat the Deadend mods that are includued in the schematic are omitted for the layout octave trimpot, starve jumper…).
