What is it?

OK, you experts, I'm thinking of buying a 1978 Musicman, shortneck, fretless bass.
single PU.

What is the model name, and what's it worth?

Short neck? No such thing.

Need more info. Serial number, finish, number of knobs - a photo would be good.

....Maybe a de-fretted Musicmaster shortscale bass? Pics?

Or maybe an Ibanez MUSICIAN?
