Hello, what I'm looking to do is have the dig dug sequence only the guitar signal, i.e. no wah or trem applied to the sequence. Looking at the schematic I was thinking of taking a wire from right after the 2n5457 to a switch and then a wire to r15, the 10k resistor. That way I could have trem, wah or signal being sequenced. I would just try this but I'm awaiting my enclosure so the pcb is not all built up yet. The question is what I want even possible, does this sound like it would work or is there a better way to do it. Thanks for any help and insight, Mike.
