so i bought a MIA p-bass last weekend. i didnt realize until after i put 45-100 strings on it, that it had 110's on it. when i put them new strings on, i got what sounded like strings rattling in the saddle. i put a peice of business card around the nut where the string rests in, and its fine. now if i want to go from 110 to 100, and i going to need a new nut on top of a set up?
