Prescription Electronics Depth Charge
Here’s a sweet bass fuzz based on the Univox Super Fuzz for Fuzz Friday. Original units used 2N3707 transistors with BCE pinout, which I’m guessing most people don’t have in their parts stash. So I laid it out for CBE transistors (2N5088s or BC549Cs should work just fine) and it will fit nicely in a … Read more
BBE 427 Distortion
By looking at the schematic it appears that this one is a mix of a couple classic distortion circuits….the core is a Marshall Guvnor with LED clipping with a tonestack lifted from Boss DS1. 2,15k reistor can be subbed for 2,2k and that huge 1000uf power filter cap could be subbed for 100uF.
Holmes H-X6 Spectrum
A rare and versitale old 3-band eq pedal with High Pass, Band Pass and Resonance controls. Schematic is avaiable at DeadendFx
DOD FX66 Flashback Fuzz
One modification is done; a transistor gyrator (Q4) replaces stock op amp gyrator due to board space.
Morula Auto Wah
Here’s a simple auto wah circuit with a pretty low parts count I thought was interesting. Not a lot out there on it, but it uses a single CD4049UBE to create an LFO and wah audio path. The depth of the effect is controlled by the LFO. Should fit nicely in a 1590B. Here’s the … Read more
