Custom Looper Pedal (true bypass) With A Unique Twist I had a buddy recently ask for help designing a true bypass looper for his two drive pedals, but with a unique twist. He wanted a third switch, giving the following combinations: Switch 1: Loop 1 on/off Switch 2: Loop 2 on/off Switch 3: Both loops on, regardless what position the other switches are in. Sends the signal back to the other switches when off. So, the third switch is a master "on", but it doesn't act as a master "off" when turned off. I thought it was pretty odd, but he had his reasons for wanting that combination. In any case, this is what I drew up for him: One glaring omission that is a major drawback to this drawing is that it doesn't include LED indicators. They are pretty much a MUST on a pedal like this. Luckily, it isn't hard to add them. You'd just use 2x 3PDT switches and 1x 4PDT (harder to find, but they're out there) instead of what is mentioned above, plus a DC jack (or battery terminal), your preferred LED stuff, and the necessary resistors. If you're in need of such a niche/unique looper pedal, give this a shot. Build safe and build awesome! Related note: Where did the thread prefix options go? There used to be a way to add "Repair Question", "Tutorial", etc. I'm not seeing those any more.
