Gambas have moveable gut frets by default. I almost thought of using a similar technique for the guitar. The problem is that the fretboard is too flat for this to make sense. On an electric guitar it's almost feasible but the frets should be made with some other material than gut. My guess is that the gut will get easily damaged or cut under steel strings. ./MiS
