Alright so I met up with the guy to check this puppy out.
Basically the reason its so cheap is because the bass had some cosmetic damage on two of its sides, very minor, but enough that it couldn't be sold new in a store. He told me that Engelhardt stripped everything off the bass, tuning pegs, bridge, basically anything salvageable and then just sold the body, which he got really cheap.
The thin neck really didn't bother me, I played on a couple basses, and I didn't have a preference between either size neck.
He also said that he would drop the price to $800. I didn't get a skeezbag feeling from him. He restores basses as a hobby, not a career. All in all though, I don't think that I'm going to be able to find a better deal for the same type of bass.
For somebody who has is new to upright I've been told this is a good starting bass. What ya'll think of that?
