More wood choices are probably available with a phone call. Stock availability fluctuates, so that would end up being yet another web page that needs periodic updates.
As for controls, I'm more surprised that they offer Strat or Tele controls than I am by the absence of any others. Seems like it would be a pretty limiting thing, inasmuch as it would influence potential body shapes. Besides, if one has the wherewithal to make a body from a blank, I would think routing a control cavity and drilling some holes in it would be puppy chow.
For that matter, I wonder how many blanks they sell. As above, anybody with the wherewithal to make bodes is beyond the point of needing someone to make them blanks. I would think the reverse would be true more often, where people would be wanting to send them blanks to be cut/routed/drilled into viable bodies. Special wood, like from a tree on great-grandma's farm, recovered from old furniture, recovered from old buildings, churches, etc.
