Re: Pros and Cons for No Tone Knob
I have a Fender Esquire. Even with stock 250KOhm pots, there is no audible difference between the back position, which bypasses the tone pot entirely, and the middle position with the tone control all the way up. I've tested this many times just to make sure; I can't hear the difference at all. Therefore I always roll back my tone knob; not doing so would give me redundancy in positions 1 and 2. I treat position one as my "treble on 10" position, and set the tone knob down a bit, which affects the tone when I switch to position 2. Position 3 also bypasses the tone pot, but it sends the whole signal through a capacitor. That is the equivalent of running a tone knob on 0 (though with a different value cap in this particular case). So, basically, the guitar has a switch that gives you 0 on the tone knob, 10 on the tone knob, or any in between value on the tone knob.
In other words, having a tone knob on 10 is the same as having no tone knob IME. That said, I wouldn't eliminate a tone knob just because I keep it on 10 most of the time. What harm does it do to have it? You might use it some time, and having it there on 10 takes away nothing over not having it at all.
If you can hear a difference between tone on 10 and no tone at all, I'd just install a no load tone pot.
