Reset loose fret ends without restringing! The end of this handy 5"-long brass tool fits over the crown of a fret, and you simply tap the tool with a hammer. Its slim 3/8" contact surface reseats loose fret ends fast — there's no need to unstring the instrument. It's also great for hand-pressing a loose fret end down while your superglue sets. Setters are available for jumbo and medium fretwires.
