These use the popular H-S-H routing, perfect for three single coils, or humbuckers at neck and bridge position. The routing is generous enough to accommodate all popular brands of pickups and electronics. Yes ALL genuine "Squier" brand Strat parts fit these bodies! These are 43mm thick and fit most of our tremolos and ALL import spec trems from any manufacturer. These are cut from crisp White Poplar, and finished with thin, hard catalyzed urethane.We think this body compares VERY favorably to bodies sold in the $150-$250 range. BUY DIRECT and save!
