I am considering a custom taropatch. My hands are not tiny, but not large for a guy either. I am wondering if 1 3/8" at the nut is wide enough for 8 strings and if a 1.5" would be better. The maker recommended 40mm. Additionally, I am considering a tenor neck but wonder how much it would add or detract, tone wise. I could have a radiused fretboard of I wish....good idea? Any thoughts would be appreciated.
