@Singe, I really think it is. I mean this is an overindulgent custom build, I do think that going for alder just because it will be generally lighter is a very lame thing to do. Swamp ash can get down to around the 3.5lb mark, but 3.75lb is pretty much the sweet spot.
@Roy I found a nice example for him to work from..

I'm sure he'll be able to get the back and front relatively dark while keeping the grain detail with a stain.. Besides the burst, I want the rest of the finish clear, so it should look great.
