I know I am new to this website, but i was hoping I could get some help. I would like to sell one or both of my basses for a rickenbacker, but I need some pricing info. One is the american made esp j-4 that is lake placid blue and in pretty good condition. Everything is original except for the input jack and the pickups, which are seymour duncan hot stack jazz. The other is a custom made black Shecter '51 P-bass. It is in even better shape, but it does need a new pickup and concentric knob. Could somebody point me in the direction of a website that prices basses, or give me your honest pricing opinions. Thanks.
