Selecting compatible wood types and ensuring standard configuration (Warmoth keeps things pretty standard with their selection) might help? I saw a few interviews a while back of the Fender Custom Shop luthiers and one explained a "bright" neck usually works best with a "dark" sounding body...and in reverse (bright body wood sound works best with dark sounding neck). I saw the post from the person who really liked the Seymour Duncan Zeph pickups but complained there was too much feedback when in distortion mode at high volumes. Do you think using a fairly dark tone wood on the body and maybe even skipping the chamber option might help to prevent feedback at the high volume levels of very sensitive pickups? Will the location of the control cavity and routing.........and maybe even selection of laminate wood help?
Thanks for the advice!
