I laid out PCBs for the Voodoo Lab Overdrive (not the Sparkle Drive) a while back. It was their idea of an improved version of the DOD 250 and kind of the precursor to the OCD if you're not familiar with it. Voodoo Lab discontinued it in the late 90s or maybe early 2000s. It was an easy circuit to lay out and build rather than pay some collector way too much for an old one on Reverb.
As usual none of my shit is labeled lol.
This has been sitting for weeks while I toyed around with other projects.
Someone else actually built one of these boards before I got around to it (the project is on OSH Park). They didn't think it had as much gain as they anticipated, but it sounded good and could be pushed with a pedal in front.
It's got a lot of volume to push the amplifier. The low pass filter in the gain section is basically full blast, so at max gain it's a real fat tweedy distortion sorta sound. As you turn it up you get more treble too. Why they didn't put a simple low pass filter after the diodes like a Rat I'll never understand. I played it with my LP through my Marshall DSL earlier. For a two knob pedal it's got some different tones as far as pushing the amp with clean signal, drive, or distortion. I haven't messed with it on bass yet. That may sound better than on the guitar since it retains a lot of low end. A mod I read about was to switch the 47k resistor in the feedback loop to 2.2k to increase the gain and cut a low end with the gain up like a DOD 250.
