Here's a weird one, build from the original idea of our friend Kurt at Spacek's Music. You already like the Horsie (Klon centaur tribute) and some of may say that the Pumpky (OCD V2 Tribute) is one of the most versatile pedal ever. Why not putting them together?
Right side is the Horsie, classic Klon design, internal voltage doubler, Germanium diodes, etc.
Left side is the Pumpky, based on the OCD V2, with a bypassable buffer circuit, and the classic grit.
4-jacks setup, so you can wire them in the order you want. If you don't plug anything in the two center jacks, they will be internally linked, pushing the Pumpky with the Horsie.
Voltage : 9VDC only. Anything higher will blow the Horsie side.
