Okay, someone help me out with this one. It's got passive electronics and black hardware. Looks like it might be Koa; I think there was another one with dark-tinted maple if memory serves. I can't find any information about one with black hardware, though. I'm driving out tomorrow to make an offer on it. The more info I have the better.
I'm not sure that's koa. The color of the wood looks a too dark, although that could be the lighting. The other odd thing is the light colored wood in the headstock. I don't think I've seen a koa Unity that looked like that. Usually the headstock is tinted the same dark color.
That particular Unity, being the passive model, is a bit less desirable than the model with the Schaller bridge/pickups and the full electronics package. It's still a nice bass, though. It's been on the GC site for quite a while. That bass is scheduled for a price drop, so the store will be willing to deal.
