With my J-74's ordered and received from JustStrings.com, I took the new-to-me old Hondo to the shop to be cleaned up, set up and re-strung. It was in need of some TLC by a qualified luthier. The frets will all be checked. The bridge is going to need some fixin'. The neck adjusted. The fret board is mighty dirty.
Even in its current condition, with the ratty old strings and poor setup, it had good sustain on the open string strums.
