I read that the Seymour Duncan Quarter Pounder pickup performs better with a 500k pot, but my TVJ Starwood Tele neck pickup likes the 250k. I found a discarded 500k pot in my parts pile. I wired the SD directly to the 500K and the TVJ directly to the 250k. I wired both pots to the pickup selector Gretsch style. It was out of phase in the middle position so I had to flip the SD wires. Now it seems to be working great. The Quarter Pounder sounds more open, and I can blend the pickups in the middle position. Next, I think I’m going to get rid of the blade selector and use a toggle switch. I’ll have to either make or order a new control plate for that. We’ll see! The only matching set of knobs I have are USA G arrow knobs. They’ll work for now. I sure hope everyone is staying cool and amusing themselves at home thru this ridiculous chapter in history! Peace!
