and sounded great. You definitely need to take the time to familiarize yourself with the EQ section. it's got a lot more to it, as compared to my GKs "bass / low-mid / hi-mid / treble" format. the amp just came in yesterday, so I didn't have that much time to play around with all those great features. All those variable "tone shaping" controls, as EA calls them, give you a tremendous number of possible tone options. The preset contour tone settings are also very usable. The built-in tuner is also very nice; it's great to have the tuner lit up right on the front face of the amp -- very easy to tune up on the fly. The gig was a soft / medium volume gig, so I wasn't able to push the envelope on the gain to see how loud she can get. I've been told by a number of players that this amp puts out a tremendous amount of clean power. I hope to take it out for a test run this week; I'd like to push it to the amp's high-volume threshold and see what kind of tonality you get at such levels. Anybody know what that tiny red light is for? the one inside the amp chassis, mounted on an internal board, toward the rear? it's only visible if you look at the amp from behind, through the rear or side air vents. maybe a pilot light for the power amp stage?
