I just got my Heritage H-535 back from Michael Tuttle. I had him re-fret it with 6100 frets. Amazing. Look at those fret ends. His attention to detail is second to none. Another shot of those fret ends. Soooooooo smooooootttthhh.... Just a hair over 3/64" at the 12th fret. His fret work has me wanting to buy cheap guitars just to have him re-fret them!
