Thanks! I don't think this is the one from Marktplaats. There are 3 or 4 of these, André always built a couple of bodies and necks for one bass to match them. I know at least two other basses like these, one with a maple fretboard and one with coromandel.
Very very versatile. To be honest, it has D'Addario Chromes on it and I really dislike flats on a Jazz, especially on such a hi fi, modern bass like this. So its exact sound still has to reveal itself to me
