Hi guys, sorry if this is the wrong forum. I'm looking at a 1980's Kramer XKB-20, fairly good condition, few dings, a small non-structural crack in base of neck region, neck straight, frets dirty but in good condition, no buzzing. Has the original Di Marzio "P" pups, comes with case. The store is asking $599. I'm tempted to offer $500 "walk out the door" price. Any input/thoughts are appreciated.
