Fun fact - I was actually at this gig. The Grove of Anaheim, 2006. He was opening for Joe Satriani and they taped both performances, although this was released a few years after Satch's taping of this was. Great performances from both guys!!
It's not unusual to see him onstage with Gibsons though. Last time I saw him at the HOB Anaheim he had a Goldtop Les Paul with him (don't remember if it had P90s or not) and he's also got a burst model... not sure if it's vintage or not. The SG comes out fairly often, as does his ES335.
