Hi, all. I'm fairly handy, and i'd like to try my hand at guilding (or gold leafing) my bass guitar. Its a USA made J bass, and i had a few questions about the process. 1) Would the tone be negatively affected at all by the gold? The gold is, of course, extremely thin, but ive heard that metal finishes can alter the tone of a guitar. Essentially, how much metal is needed for this to happen? 2) What exactly does fender finish the USA made basses with? This is a discontinued custom shop model, the fender custom classic jazz bass. Im not sure if that matters at all. Thanks!
