Hey -
If you're a KSD person, and you want that combination, I've got a KSD jazz proto you can buy (check the link in the signature).
Ash J body, maple board, and maple neck - 6 strings...all you'd need to buy is the pre-amp.
But you're probably looking for a 4 string....
As for tone, ()smoke() is right on the money! Maple board for snap, but you need to get some wenge in there for killer tone. Ash/Maple/Maple is very bright (as is my KSD), and it's hard to get a full bodied tone that will cut through the mix and still have enough snap to make a great slap/pop.
The BEST combination I've heard lately is a Pulcinella with a wenge neck, ash body with maple top. I'd have put a maple board on it for a little more snap.
For tone, you gotta have something like wenge in there to balance out the brightness. Nordstrands are an excellent choice as well for pickups.
Good luck!!
