So tomorrow night, I will have the chance to try out/purchase a Spectorcore 4 string fretless bass in an orange/amber color. This will be my first fretless if I buy it, so I'm thinking the lined board is a good thing. The bass is being sold for $400 with gig bag, strap, and strap locks included. From what I can tell through my research this is an excellent deal based on price of a new one. My question is whether you TBer's have had good experiences with this bass (if you've tried it) or heard about whether it's a good instrument. Also, what are the must-ask questions when buying a used bass?
