I had fret buzzing on the 2nd fret G string of my les paul after raising the string gauge. My luthier showed me the first 5 frets all have indentations where the string meets the fret and offered to replace the first 5 frets for $60. I said okay, is this a bad idea? My guitar teacher said all it would need is a fret dress but I'm guessing a new fret is even better? Is this true or is there something bad about getting new frets?
