Hey all. I have a guitar with two humbuckers that has a separate volume for each pickup and a master tone. I do not know if this is standard–it’s been a LONG time since I had such an arrangement on a guitar–but in the middle/both-pickups-on switch position, turning either volume down to zero kills ALL the volume. Is there a way to rewire it so that rolling down one pickup only rolls of THAT pickup, so I can blend the two however I want?
