I put better pickups and a better pre-wired control plate and wiring harness assembly in one of my mod platform Bullet Squier teles. Sounds better, tone rolls off better, everything is better. But it does one strange thing--when I roll the volume back, it goes from 10 to 8 to 6 to 4 to 2 and then suddenly back to 10. What the hell? I'm sure it's something stupid I did with my soldering iron. And I'm in no hurry to fix it. But when I do, where should I look for my obvious bonehead mistake? I did nothing to the wiring harness other than connect the pickups to it.
