I have a strat... and i want to install something from Stew-Mac. It's a "black ice" overdrive box. Basically.. (you can find it at stewmac.com) it turns one of the tone knobs into an overdrive knob by replacing the capacitor on one of the tone knobs with the Black Ice. this isnt hard, as i have replaced a capacitor before, but i dont know how to wire it so that i can make the other tone knob the mast tone.. for all pickups...
