Thanks, guys. I'm so jazzed about my new guitar (pun intended).
I've installed a gazillion strap buttons before but somehow this new territory had me feeling sheepish. It's good to hear that I can move forward as usual. I'll probably pin the second button to the heel of the neck.
The solid construction of the 575's top is really nice. I have a laminate Collings I-35 (their version of ES335), which is a smashing, lovely guitar. But the tone out of the 575 is very different--maybe due more to the fully hollow build rather than the material. But in any case, the new 575 sounds great, and very different from the Collings, which is what I was hoping for. I'm intending for this guitar to be mainly for traditional jazz playing.
