A technician who is doing work on my EB-0 project has just called me up to tell me that 2 volumes and 2 tones are not possible. He says turning down one vol will always shut down both pickups. And that this configuration is never done. Using this attached diagram and alligator clips I had this working a few days ago. So I'm really suspicious of what he's telling me. Can anyone give their opinion on this? I need some facts before I go back to him and I start demanding things. thanks. Just in case your wondering, I've added a second pickup.
