I do not have UAS, I do not have UAS, I do not have UAS, I..., I, really like Collings.
But I'll play the hog Collings I got from the Marketplace, and figure the koa one can't possibly be better, right?
Keep telling yourself that... or "not better just different". I lucked into a "2 for" trade for a UT3K. I have a lot of nice koa ukes but the Collings has a chime that to me sounds kind of piano-like. It's not my loudest koa but by far the nicest, cleanest, most balanced. And I would think the satin finish would be lighter than the high gloss (but I love the dimensional look Collings UT3K's have. It's almost like you can see down into the valleys between the hill peaks in the grains. LoPrinzi is the only other Koa I've ever seen that has that same 3D look.
