PedalPCB ADHD with bypass/Fulltone OCD

I am a big fan of this pedal. I previously built one and it went off to California so I built another. You can roll the gain all the way down to zero and the pedal is a transparent OD or boost. You also have a toggle which goes from mild aggression to pissed off murder wasps. The pedal worked immediately on the PedalPCB platform and even though I socketed the Ges and the transistors, I have no reason to try any others.

The enclosure is from Tayda; light blue powder coated. The knobs are from LMS and they are red and 20mm at the base. I did the decal on my QL-1110NWB printer. I went with Switchcraft jacks. If you were thinking of building one... do it!

Have a great week everyone!

Nice build. I’m a fan of the OCD as well. It can literally do anything from boost to rock. Is this based off any version? I thought the original used silicon diodes…hence the reason for the light blue germanium OCD. Would be cool to put different clipping options on a switch.

I intend to put one of these on my board permanently. It does the work of my Wampler Plexi and my MXR Timmy. I like your idea. I will just be reading the boards for a while instead of building. Maybe Someone else on the board would know how to add clipping options - Probably someone like @Chuck D. Bones. But honestly three knobs one switch and it is glorious. I think it is perfect, and I am also a very big fan of the PedalPCB Tommy III.

I have both the regular and Ge versions of the OCD but I have not opened them.

Pretty sure it’s the same as this except with your diodes. Question is…what interesting pairs and which type sounds best.

Thanks for the visual. Yes, I need to get my breadboarding going, or buy one of those diode boxes they sell at LMS.

Get the breadboarding going;
also, you can build your own diode-clipping boxes with some dipswitches or rotary switch and some vero/perf.
Rotary and a wild six-clipper option here.

Bluedmc's got it with that diagram.

Here's how it would look with some diodes instead of resistors:

If it's just clipping to ground with a no-diodes option, you could just use a SPDT on-off-on.


Try this. Or this.

For another clipping-to-ground option where you need not worry about the middle position having a higher forward voltage compared to the others, use an on-on-on switch to switch between 3 sets of diodes.
