Got an guitar electronics question for ya'll; In putting the harness together for my latest build. I have 2 magpups going thru vol and tone pots into a 3-way and that 3-way output then goes into a second 3-way. A pre-amped piezo feeds into the other side of the 2nd 3-way, and then that 3-way output goes to the jack. The problem is, I get a pop when switching the 2nd 3-way from magpup to piezo and back again.... I think a correctly placed cap or resistor would solve the popping, but am curious as to where I should put it, resistor or cap and what size would suffice??
Does the popping sound like when unplugging your amp cord? It may be a switch quality issue.
