I've seen quite a few stunning Balance K's, but this one really stands out as one of the most exceptional -between the stunning wood, the beveled peghead, and the extra cool custom electronics.
In fact, this bass specifically pushed me over the edge, into ordering my own Balance K.
If the neck was a little narrower, and there was ebony in it, I'd have been hoping I could meet your price. Regardless, it's too awesome to not sell.
Serieshead or not, I can't grasp how you could let such a masterpiece go... but good luck with it. I've not doubt that it'll make someone a very happy camper!
