I was at my local music store and noticed that they had a pre-lawsuit Ibanez Fender Jazz copy. It had a few nicks here and there but, played beautifully. The pre-amp was a bit weak even for a passive bass (my SX puts out more). Anyway they are asking $449.95 and I think this is a one in a million chance. I have a few basses and I was going to upgrade a Gary Willis GW35 that I don't play anymore. Do you guys think that trading in a Gary Willis low end is worth the vintage Ibby?
