I am a Trey lover, but gotta say I prefer Rick's PRS Hollowbody into MB Express 50 vs Trey's Lang into the Trainwreck. Of course Trey's tone works great with TAB and Phish.
I would open mouth kiss either one of them if I met them. Just saying.
No pedals were signed during this performance, so we won't know how the gain was set unfortunately.
