I don't need a blender! I thought I had it all when I found a split shaft rotary switch. It'd have been perfect - turn the second tone knob to switch between series and parallel operation in positions 2 and 4, don't ever have the knob sticking out.. But it doesn't work. The switch seems to be of such abysmal quality that I had to scrap that approach (I've tried everything. Everything! To make it work. It just gulps 90% of the signal) and it's the only one of its kind with something that vaguely resembles a reasonable price tag, so I'm back to a push-pull pot with a pot part I don't have any use for. I want master tine and volume, so what the hell is there to do for the third knob? Again, I don't need a blender and Mr Dan Armstrong had some good ideas, but his mod gives me more options than I want! So yeah, I'm kinda out of ideas... please help me?
