Hi all, I searched for this and couldn't find it hopefully its not a repeat. I have converted my strat to the tiger layout with a push pull pot to split a Duncan pearly gate and little 59. I installed a super two permanently split in the middle position, with a stacked tone for bridge and neck, and push pull for middle tone and to split the Duncan's. I also used a 25k push pull on the volume to switch the loop in and out. My problem is the volume won't turn all the way off. I've grounded everything the same as the Wald tiger schemo. Its my understanding that push pull pots are just pots with a switch mounted to the bottom and there operation entirely independent. Is there some extra grounding to look out for with this type of pot? I have tested the pot with an ohm meter. And it appears to be working. Any thoughts, help, answers would be appreciated. Thanks Greg

I do know running a 25K pot is because of using an active low impedance buffer in the guitar, did you use a buffer in the circuit? that may be the issue... otherwise sometimes you get bad pots, even new. I was actually wiring a guitar for a friend and the pickup was screwed up and the push pull pot too. He got a new pick up and pot and it worked just fine. I also had a bad DPDT
switch with my latest wiring job in my fleet of guitars. it is strange yes to have that much go bad, but I know now how possible it can be.

Yes, I used the CB-1 I had in my old guitar. I did order a new pot. I'm gonna try that next. It just sucks you can't find parts like these in town. Thanks for your input.

Yes that was it. I checked that a few times it looked like it was, but once I dug deeper there it was. It gets pretty crowded in there with all those wires. Thanks. :P
