Gibson Basses / Re: 1 meg pots and TB Plus pickups
« on: August 02, 2016, 11:23:31 PM »A tone control is a passive treble bleed circuit. With the tone control on 10, there's no bleed of treble frequencies to ground, no matter whether you're using 250k, 500k or 1meg pots. They're all equally as bright as the pickup will allow.
..As bright as the pickup and tone pot will allow is more correct. Correct me if this is not the case with TB+ circuits, but with the tone pot on 10 you bleed the trebles through whatever resistance your pot value is to ground via the tone cap. Not that I'd ever bother changing the value to 1M, because as you said the pot will have more like an on/off function and have a lot of useless travel, but it answers georgestrings' question.
