I've decided that Teles by design are simple instruments and over-complicating them with too many options are just not for me. After trying push-pull pots for series/parallel, TBX with a variety of capacitor and transistor schemes (Doc's mod, Phostenix, and all the mods recently in Premier Guitar), I've gone back to a simple volume/tone/3-way switch configuration What the hell was I thinking? In the end, the option of having the two pickups in series wasn't that great of a tone, the bass roll-off from using the TBX was not tonally pleasing, introduced hum (0-center detent was dead quiet) and just not worth it. I did make my tone pot no load, which is a subtle, but simple mod that I believe IS worth it. I'm sure there are others that would disagree and find these mods really useful, but just thought I'd save some people some time from my personal experiences.
