I recently bought a wonderful 1960 mono 355 from OK Guitars in the USA. It is perfect, apart from a recent refret with very tall stainless steel frets with rather sharp ends, which neither I or OK Guitars liked. It was uncomfortable to play and I was inadvertently bending some notes sharp, especially on the G string. Just picked it up from Charlie Chandler's Guitar experience having had about 1/3 of the fret height plekked away and the ends softened. The result has transformed it into a brilliant player. Taking that much material off stainless steel frets by hand would have been a bit of a task for a luthier, and the plek machine, plus hand-finishing has turned out great. Its my first experience with having a vintage guitar plekked so I thought I'd share the positive experience.
