Double Drive Overdrive


Here's a project for non-true bypass freaks out there. It's the Tech21 Double Drive OD. Square pads of the diodes indicates the CATHODE. FET switching is adapted from Boss pedals switching system. Use 2SK30A for switching FETs and BC945 for the bipolars. Footswitch is a normally open type. Layout is verified!. True bypass version to follow.
