When someone else is paying you to build them what they want I do my absolute best to give them what they want. The design's I don't change to any great extent and my own pickups and pre-amp are my preferred option in that department but the woods are entirely up to the customer unless it just won't work.
I just love black limba it is great to work with sounds great and looks brilliant the only downside is that it is getting difficult to get the good stuff with good colour and grain.
I have a few pieces which are quite heavy so I intend to make a chambered Limba bass no top or back. The limba I have for this is very nice indeed so I am sure you will approve when I get round to it.
