I had a guy ask me about a fanned fret bass, I've never tried, but I'm ready to mess up a few fingerboards to give it a shot. I thought I would use a 34" scale for the high end and a 36" for the low. Does the 12th fret run perpendicular (like a normal fingerboard) and the higher frets and lower ones fan away? Does anyone have an easy proven way to pull it off? Do you mind sharing?
