I have just started a new bass project, a fretless sixstring. The first step is thinking about the design and the woods. You can see the design on the picture left of this text and I am pretty sure what sorts of wood I will use.
1. Planing the construction, wood combination and electronics:
The bass will have a neck through body design, but the neck won't be visible from the frontview. I have already bought a premium bookmached spalted maple top.
The top wood
The neck will be made of wenge maybe with some laminates. I will use a ebony fingerboard, a matching spalted maple headstock. The body has three piece sandwich contruction made of spalted maple top, a wenge core and a purpleheart back. In the center of the back, there will be a laminate of flamed maple, as known by Ken Smith BSR neckthrough basses for example.

The pickups will be Häussel, Rough Crystal or Basslines.
