First bass built for me buy the guys of Cobelens & de Bruyne, of whom I am an endorser:
Maple body, merbau top, maple neck, rosewood fretboard, Seymour Duncan Basslines soapbars, Aguilar OBP-3, Wilkinson tuners, ABM bridge.
Because I'm not 100% satisfied, so they're building a new bass for me that's smaller, lighter and has nicer wood:
Same pickups, preamp and hardware, but it has a downsized body made out of ash with wengé laminates, spalted birch top, maple/wengé/greenheart neck, ebony fretboard.
