Kay 5-String S-51B Serial # 23903 "Chubby Jackson Model" Purchased circa 1994 from Bill Merchant used on a few gigs in the 1990s, kept in home since. The fingerboard is wider than the neck to accommodate the 5 strings. About the work needed: The top arch has sunk near the right F-hole, and the top has become partly unglued on the sides. I took it to Finlay and Gage, who said the top will need to be taken off, re-pressed and re-glued with some work on the sound post. Since I am not interested in playing the 5 string anymore, I am selling for $500. Will consider trades (I may be interested in a 5 string electric fretless).
