Hello all: I have set my eyeballs on the latest "got to have it" bass at a local shop in my neighborhood. It's going to cost me a trade-in in order to grab it. I have this Warwick Corvette 5-string fretless that I am willing to part with. I asked the shop over the phone how they make their assessments for trade in value. They mentioned using the Orion Blue Book value. When I asked them how much that was, they said "you'll have to come in." OK, that's fair. But I would like to have an idea about my approximate trade-in value before I go, just in case they try to lowball me. Anyone care to comment on what they might feel is a fair trade-in value for my bass? It is in perfect condition, given its, somewhat limited usage. Anyone have an Orion BB that they could give me a price out of? I'm thinking about $650-$750 in trade. I paid $1250 for it. Thanks!
