Re: Does 2 vol 2 tone wiring suck tone?
The other thing, too, is whether the effects on the tone are good or bad. Maybe it's helping the guitar's tone to have those pots in there. Remember that this is subjective; we don't have to be true to anything except the sound that's in our heads. We're dealing with the instrument itself, not some cable or preamp down the line that might be coloring the sound in some way. We're at the origin of the sound, and we can shape it however we choose.
I've heard people try to sell pickups by claiming, "They give you the exact, natural sound of your guitar -- no more, no less." Well, they'd better be giving me something other than the natural sound of the guitar, otherwise I'd might as well be mic'ing the thing like an acoustic.
So, when you ask if those four knobs are sucking tone, my response is, "Well, if they are, they're sucking it in just the right way. If you know what I mean."
