Fulltone PlimSoul
Schematic is avaiable HERE. Note that it is highly recommended to use a 10k pot for Sustain to avoid noise and dead spots in the sweep.

Fulltone 2B
Schematic is avaiable HERE. Note that this is a buffered effect so the offboard wiring is a bit unusual.
Fulltone 2B
Happy 2022, everyone! Here’s a buffer/booster from Fulltone. Engaged it’s a booster with an interesting controllable germanium soft clipping setup, and when bypassed the diodes and gain control are shorted, creating a buffer. If you’re just after the boost and want to skip the buffered bypass, just ignore the two Bypass pads and wire it … Read more
Fulltone Mas Malo
For Fuzz Friday, here’s Fulltone’s take on the Big Muff. The main differences over a regular BMP is the input and output stages. The input stage has it’s own gain control and the output stage is a JFET-based gain circuit. Also the volume control has been moved immediately after the tone stack, with the output … Read more
Fulltone Ultimate Octave
Happy Fuzz Friday everyone! Had a request for this one. It’s basically a Foxx Tone Machine with some value changes and a couple additions, namely a switch to shift the range of the tone control and the octave switch is a footswitch. Here’s the schematic for reference.
Fulltone OCB
What’s the OCB you ask? It’s the bypass buffer circuit from the new version of Fulltone’s OCD. It allows you to switch between regular true bypass and buffered bypass. There are 2 versions: The first (smaller) inverts the phase of your audio signal when engaged (in bypass mode phase isn’t inverted). The second (larger) adds … Read more
Fulltone OCD V2
The latest iteration of the OCD has quite a few differences from the earlier models. There’s an added transistor stage at the output after the volume control, and a JFET buffer that can be toggled for buffered or true bypass. I’ve laid it out so it will still fit in a 1590B with board mounted … Read more
