A customer brought in the Gibson Gospel with intonation problems. Strobing revealed that the intonation was off but I wasn’t prepared for how far the saddle was misplaced. Using the “intonator” I located the correct positions for each string. It was nearly 1/4″ off on the bass side! Not entirely believing this, I double checked it with the “saddlematic”(and against several other Gibson acoustics.) My plan is to fill the slot and rout a new slot in the correct location.
