Just in general...
Sometimes, a rare guitar is rare because it didn't really "work." Of course, with enough playing time, you can determine if that is the case, but I'd want to spend at least an hour noodling on the thing to be sure.
Almost all gear sells, use, for about 50% of what it sold for, new. I would not pay a cent over $1300, and being the cheap bastard I am, I'd want to get that guitar for under a grand. Just me, but I thin 1600 is way too much. When I experiment, I want to be sure I won't get hurt if I decide it's not for me and I decide to re-sell.
Yeah, I'm a mod. But I'd rather be a rocker.
