Hi Friend -
I've always loved the OCD pedal circuit but...
It's one of those pedals people argue about endlessly. Some players swear it's the perfect blend of overdrive and distortion. Others think it's too harsh.
What always bugged me was this: there have been several versions over the years, each with slightly different tone and behavior. If you wanted to compare them, you'd have to hunt down multiple units.
So I decided to build my own take. Not a clone of a single revision - I wanted all the versions inside one pedal so players could choose for themselves..
The second thing that pushed me was tone control. The original has one tone knob, and yeah, it's part of the character. But I've always believed players deserve real EQ control. Bass and mids matter when you're dialing a pedal into different amps or guitars. So I kept the original tone control (now called (Treble) because it defines the voicing of the high end frequencies, then added a full three-band EQ so you can shape low end and midrange in ways the original simply can't.
The final piece was MOSFETs. A lot of builders, and this original circuit, use MOSFET transistors as clipping diodes. It works, but you're not getting true MOSFET gain behavior - you're basically using the part as a fancy diode. I didn't want shortcuts. If I was going to use MOSFETs, I wanted them to behave like real gain stages, the way amp-like pedals do. So I built an entirely separate MOSFET gain circuit into the pedal that can be switched on and off - you're essentially getting two TOTALLY different types of gain circuits here.
That's why The Compulsion Drive exists. I love the OCD, but I always wished it could be more consistent, more flexible, and more amp-like. The TCD is simply the pedal I always wished the OCD could have been, as great as it is.
It just released, and I wanted my core audience to get first look.

P.S. - The internal DIP switches let you dial in every version of the circuit that's ever existed. One pedal, all the versions.
