I'm building a looper for my pedals to toggle between two effects loops with one switch. I cant use a traditional looper where you need to hit two sitches to turn one loop on and one loop off. Anyway, attached are two drawings...one is a 4PDT switch with grounded inputs for the loop that is being bypassed and the other is a simple 3PDT. I think the 4PDT is true bypass, but I'm uncertain since the bypassed loop is still connected to the circuit via ground, but that wont affect sound in the selected loop, will it?
Do both switch drawings look like viable true bypass options? Any helpful feedback?
