Boss SD-1 SUPER OverDriveVerified

From the post
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).
