I have a bllodwood (Satine) neck with an ebony fingerboard on an Ibanez basswood body with a Nailbomb/Slowhand/Cold Sweat set and it sounds great. The neck is quite bright, but probably not much more than maple/ebony, at least with the basswood.
It does look great though. I have a couple of interesting necks coming from Warmoth in a few weeks, they are a goncalo alves tele with a kingwood fingerboard and a wenge CBS strat with a bloodwood fingerboard. I have the body for the strat, it is swamp ash and i have finished it in black relic (just did the lacquer cracks, the chips and sanding come next!!).
