I love the frets on my '73 S-100. They're low but not quite in "fretless wonder" territory (I like those too on some guitars). My '71 OTOH was refretted by its previous owner with tall & narrow frets…a bit too tall for my current taste. The guitar is such a livewire that I don't wanna get rid of it, but I may have the frets dressed down some. Not too far: low & wide is good and so is tall & narrow, but low & narrow (a la Teisco) is yuck.
