Hey there...I finished turning my fretted BC Rich into a fretless on Saturday, gave the fretboard 8 coats of polyurethane, and as it turns out, everything's great except for the G string. Seems no matter where I play it (unless it's open) the string has barely any sustain. Is it possible that I have too much poly on the fretboard? Or would this be a totally different issue that would be harder to resolve? Any help you guys could give would be greatly appreciated. Thanks!
