This guitar has really blossomed now. The notes are a bit richer and deeper, and have a nice 'round,' warm sound to them. The sound reminds me a lot of the '68 ES-175 that I used to have a few years back. I play in a big band, and when I roll the volume down to about 7 and the tone to about 5 and play on the neck pickup, I get a pretty convincing big band rhythm 'thunk.'

I thought the 275s were semi-hollow, but yours looks deep - is it fully hollow? It is gorgeous regardless, and good luck with it.
