That is one sharp looking bass - many congrats!!! I like it!
You don't like Elixirs? I think they're beautiful sounding strings, but they cost too much IMO even though they do last longer than uncoated rounds. All my SR's have Prosteels on them, and they are fairly inexpensive strings, but they start going dead after 2-3 months. I love bright strings on Ibby SR!
The only thing I don't really care for in the Premium SR5 series basses are the 2x3 headstocks ... I wish they had 3x2 like the standard models.
You know, I seemed to like the Elixirs when they came on the first ATK I bought back around 2008, though it was partly because I'd been using steels prior to that and the coated Elixirs felt smoother on the fingers by comparison. I guess I just felt like some of the basses that I had Elixirs on seemed to come to life a tad more and sounded a little less subdued when I swapped them for non-coated strings. But I've become rather fond of the tension and feel of Sunbeams the last couple of years, so it may be partly that I'm biased towards the familiar now. We do get set in our ways about certain things sometimes.
I've really become fond of this bass after recording with it some, btw. So comfy to play. In terms of the intersection of feel, sound and looks, it may be my favorite bass that I've ever owned.
