So I am considering selling a couple of my basses: Guild SB-202, Candy apple red w/ white pg Washburn Force 8 Chicago. BBR Fender MIM Jazz fretless with painted lines, sunburst The Fender I can see similar used prices online because they are relatively common in the used market and still being sold new ($600), so used around $400. But the other ones I have no idea how to price them. They are in very good condition, but I don't know if there is a collector's market. Neither are on eBay or currently up for sale at Guitar Center's used section. I saw this http://oliviasvintageguitars.com/bass/guitars/2073/ and either I am holding a valuable bass or this site is waiting for a sucker. I can't tell. Suggestions?
