An update.... after letting things settle down, I've done a bit of setup work. A 1/4 turn tighter on the truss rod, and some adjusting on the bridge and it's playing nicely. 5/64 for the low E string, about a business card worth of relief around the 8th fret. It's much closer to my 535 now in feel.
RE: the sound. I'm actually surprised it's darker/deeper sounding that the 525, even though they both are maple and have Lollar P90s. I brought the poles up on the G B and E of the neck pickup and took the low E down a bit. Sound is more balanced between strings now. It rings very well. And just like the 525, if you have the amp up a bit, you can get it to howl on a nice A or D string! Eternal sustain!
