I dislike the pickups and control plate, but as it isn't 'original' it could be a great base for a new bass. Ad a black control plate, prettier control knobs. other pickups? Mudbucker covers with something underneath?
Not too fond of that wooden controlplate either. A black one would certainly look better.
I have no problems with those pickups or how they look. Black with chrome/metal details sort of rhymes with the looks of the original lo-z pickups
Neck and body may certainly stem from that era and I don't doubt that a Gibson employee built it, but perhaps later than 1973 from a guitar husk lying around (as a lot of these employee projects start). Pups, bridge and even the fact that it is fretless indicate a couple of years later to me. In '73 Jaco's influence on the popularity of fretless playing had not yet been felt.
That could very well be the case. Not that it matters much.
Not only the body and neck, but also the pots and wiring loom look all period correct.
Having said that, I'm not going to buy it. I really don't need another bass.
But I think Ze Kollektion could do with another odd duck.
It comes from the same factory, has the same wood , same construction, same logo. etc
It was never "upgraded" or "modified". This seems to be in the exact same shape as it was built many years ago.
Go for it Uwe!
