The factory wiring jobs done on most guitars are horrible. With a little bit of solder, wire and a couple of respectable capacitors, practically any guitar can gain fresh life from a good wiring job. Here are some of the wiring schemes I have designed and/or use on my guitars.
Most of my wiring designs make use of a progressive treble bleed circuit. Instead of the commonly-recommended fixed treble bypass capacitor that blindly jumps any and all high frequencies past the volume pot, this arrangement passes highs relative to the position of the tone knob. I find the arrangement to be much more versatile and sound more natural then either a traditional treble bleed or a no-bleed arrangement. The Telecaster wiring diagram shows a nice side-by-side comparison of the various wiring arrangements in the simplest possible circuit (one vol, one tone).
