I have a JB humbucker in the bridge of one of my guitars and, similar to one of the other posters here, I am not getting really good pinch harmonics.
I've read somewhere that with tone controls, you are always sending some of the signal to ground. On my guitar I did the spin-o-split wiring where you can use a tone pot to control the amount of split. I'm doing this with both my neck and bridge pickups and I like it a lot. I can dial in any amount of split I want from full humbucker to split coil mode for the single coil sound. At least I thought I was going full humbucker with the knob at 10.
Am I actually sending some of the signal to ground with this control and therefore never at 100% humbucking mode. And if so, will this account for my not being able to get really good pinch harmonics?
