Hi, this is my first post, and I'm a guitar player who's never played bass, so you get to laugh at my laughable errors. I've been looking at getting a bass, have tried out quite a few. I'm in no rush and willing to spend months learning about basses before I pick one. In my adventures I've come across a violin bass made by Ibanez that the owner's looking to sell. I believe it's an Ibanez model 2357, made some time in the late sixties or early seventies. It looks, feels, plays and sounds far better than the modern Hofner Ignition. It also has enormous neck dive, but I gather that's normal for this type of bass. The neck seems to be perfectly straight. The action is good. The wooden body parts seem in excellent condition. Now for the bad news. The binding is yellowed and cracked in places. The scratch plate clip is rusted. The height adjustment mechanism on the bridge is very rusted. The bridge would surely need to be replaced. The E-string screw on the bridge pickup is completely rusted. That's not a good sign for pickup health, though it sounds okay when played. The other pickup screws look a bit tainted. I assume if I opened it to look at the wiring it would be a sad sight. The neck plate is in good condition but the plate screws are so worn that I doubt a screwdriver would bite. The neck has obviously been off and on quite a lot. Owner is asking $600. My questions for you experts: What is this bass really worth? Is this vintage violin bass worth spending the money to fix up? Where on earth do you get replacement parts? What do you think?
