I have a Strat with Ralph's vintage style pickups. It's standard Strat wiring, except with the bottom tone control swapped over to the bridge pickup instead of the middle pickup. Flipped over to the bridge pickup, ALL the bass is missing, the tone control acts like a volume control for most of its sweep, and the output level is noticeably lower. Up until now, this was the most usable Strat bridge pickup I've ever used, and I loved it. I grabbed the backup guitar to get through the night, and I got home too late to crack it open to take a look - now I'm sitting at work stewing. Any ideas about what might be wrong?

Your cap has either come disconnected or gone bad?

I was thinking the same thing. I'd check for cold solder joints, especially on the back of the pots. It's sometimes hard to get those things hot enough for the solder to stick well. A little flux goes a long way to help on those.

I replaced the bridge tone pot altogether, and reflowed the solder to the leg of the cap at the neck tone control as well. No joy. Thoughts?

Try a different cap?

Since there's only one tone cap in a Strat system, and it works on the neck pickup, it has to be OK, doesn't it?

Ok, how about moving the wire back to the middle pickup position on the switch and see if it does the same thing?

Just trying to cover all the bases. Cool

Switched the tone control to the middle pickup - it worked fine. It finally occurred to me to slap a multimeter on the pickup - it reads open. It made noise, so that never even occurred to me. I swapped out another bridge pickup from another set (of course I have an extra set of Ralph's vintage pickups lying around) and everything works as it should. Seems as though I've accidentally created a Strat version of the Roy Buchanan Nancy pickup. Should I start bottling my sweat as a magical mojo inducer?

I was going to suggest trying a different pickup next. Glad you figured it out. Smile
