What on earth should I do? I cant even turn the screws how do i get the rust off safely... I just found out today I could adjust my action through this thing...the bridge... I always thought i needed a truss rod to do that since mine was a bolt on it didnt have one so i thought i never could fix my huge fret buzz...I cant even turn the screws...im screwed. I remember in chem or something like redox or something pshh.. i forgot someone help?
