It's Spalted Something for sure.
Could be Maple, Beech, or Birch. It's impossible to tell from a picture with absolute certainty. But if I were pressed for an educated guess, I'd lean more toward Birch for the native color of the wood, and the character of the flaminess.
If it turned out to Maple, I would not be entirely surprised though - wood is wicked that way.
As for the scale length, we sure don't make a ton of 36 scale basses, so it probably limits the available audience. But then again, since we don't make that many, it might have a higher demand for those seeking that particular feature. I'm really not much help in that area, sorry.
