Boss SD-1 SUPER OverDrive

Since the Zakk Wylde overdrive from last week was based on the SD-1, I figured I might as well go ahead and lay that circuit out as well. This doesn't have Boss switching so you can wire it up for true bypass. I've added some extra pads around D3 if you want to change that to a germanium (which seems to be a fairly common mod to this effect).

  12. The overdrive seems to work, but the drive control doesn't working at all. It sounds like at full drive but there is a weird sound at the end when you let the strings ringing, like when the batteries are dying.
    Any clue on what I could have done wrong?
