Hi, I am thinking of making a bass into P/H like amerikan deluxe precision,.,. mine its a P/J configuration bass(ESP B50) so i think i need to move the bridge down some more (looks cool and spaces) and make a humbucker space. Then it will have some screw holes caused by moving the bridge.. Does it affect the sound if the body has holes in it? Is digging the body part expensive?? Thanks..
