Pink Jimi Photon 'Weetie Pi

Here's a really cool and versatile dirt pedal design by Pink Jimi Photon. He's made a lot of contributions to the DIY community and whips up some cool stuff. Check this thread on FSB for the schematic and Jimi's description of the circuit.

Pink Jimi Photon Photonic Juergulator Mk 2

Here's Jimi's (second) take on the Harmonic Percolator circuit. Like the original, Jimi's circuit uses germanium and silicon transistors, but with much more attainable components. Here's a link to his schematic, and be sure to read his notes on changing transistors. The 47µ cap he references is located between the 2 transistors directly in the middle of the board. I've added polarity protection and power filtering. Pots can be mounted from the solder-side of the board using right angle PCB mount pots.

Pink Jimi Photon - Dirty Bad!! Model One Driver

PinkJimiPhoton from over on FSB shared this circuit he came up with. It's a bit of a Fuzz Face variant, but sounds fantastic. His original schematic doesn't include a master volume control, but one is easily added (if you want to add to the offboard wiring mess... lol). Use an A100k pot and wire the board out to lug 3. Lug 1 to ground and lug 2 becomes the new out.

Here's Jimi demoing it.
