So I'm looking at getting a Carvin B4 sometime in the near future. (Carvin B4) I'm planning on using this bass for jazz and funk, I try to avoid rock whenever possible, and for that I have a precision bass (which, sadly, I use for my jazz playing at the moment). I'm wondering what wood for the body would give the nicest tone for jazz. I'm looking for warmth and depth, with excellent balance in response between low and high frequencies. I'm looking at walnut, mahagany, and swamp ash, but the ash seems like it may be a bit too snappy. Any input?
