Those KXK guitars are, er, nice, but far too metal for my tastes. The one that Karl Sanders from Nile is playing is ridiculous - the headstock looks like a stupid polearm! Man, some of those guys get so carried away...
Soloway is a cool guy, and I've traded e-mails with him some years back. His guitars aren't necessarily for jazzheads only. I think they'd fit well for the music I play - a weird mix of bands like Isis and Neurosis, Jesu/Godflesh, Failure and Deadguy. Thing is, they're a bit pricey as is, and I think he'd charge me more to build a Swan with a slightly longer scale that's tuned B-to-B.
Myka is looking very appealing right now, because I'm in New Jersey and he's not all that far away from me. Hrm...
As far as building my own, that's coming. I'm an apartment dweller right now, so I don't have room for any serious tools or anything like that. I plan to continue reading as much as I can until I can purchase a house with a garage, which will hopefully be within the next five years. I'm asking about custom builders because my fiancee is looking to get me a nice guitar as my engagement "present" (I got her a ring, she wants to get me a guitar - pretty sweet deal, no?), and I've always wanted a really nice baritone.
