So I got a bit carried away at last nights gig and decided to play a bit of slide with my beer bottle (last song shenanigans). Opened the case this morning to give the guitar a rub down only to find string indents in the frets under the b string 12th fret up and the top e string 7th fret up. I have carried out a complete fret dressing and have managed to remove the indents so alls good but I have done this many times with other instruments and never had this problem are the frets abnormally soft?
