Tools, Tones and Toys for Guitarists
Time for some bass distortion. This one’s a RAT with an input buffer and soft clipping instead of hard. Apparently these were built on the same PCB as the Fat Cat and LA Metal. For a drilling template just use the Fat Cat one.
A rare and versitale old 3-band eq pedal with High Pass, Band Pass and Resonance controls. Schematic is avaiable at DeadendFx
I’ve seen a few people playing around with discrete opamps in classic circuits, and thought I’d give it a go with one of my favorite circuits, the classic MXR Distortion + (or DOD 250, etc.). The typical 741 opamp has been replaced with Joe Davisson’s Diode-Compression Opamp. The 6.8k resistor in the bottom left corner … Read more
Here’s Vertex’s Trainwreck-style pedal. Essentially a modified Ibanez SD-9. BJT input buffer, opamp gain stage, followed by hard clipping, a fixed BMP-style tonestack, and JFET output stage. Schematic over on PedalPCB.
Here is a variation on the Rat theme. I wanted to do a MOSFET Rat since I have a few CA3240 dual op amps lying araound and I like the sound of MOSFET transistors of hard clippers. Caps is enlarged a bit for a bit more low end and a switch for a 10uF running … Read more
