New Schematic

A project log for PiModulos

A module EHX Big Muff Pi clone PCB, the PCB can be populated with any version of the transistor Muff circuit

Here is the newly revised schematic for PiModulos V2:

Most notable revisions are a much neater layout and the components are numbered the same way they would be on classic Big Muff pedal PCBs and schematics. This revision still has the tone switch, I'm planning on keeping it if I can keep the PCB a certain size with it on there, otherwise it will left out.

As for component choices and values, the schematic aims to match the Skreddy Mayonaise variant as close as possible. Some component values for some capacitor types are hard to find, so some compromises were made (e.g going with the closest value). I plan to try different component values when testing and assembling to get as close to the desired sound as I can.

Moving on to layout, I'm in the middle of it currently and will be posting a completed board and OSHPark quote soon, so stay tuned!!!
