Hello again, The Rivera R55-112 combo is the amp I'm looking at most seriously for a backup amp and a grab-n-go 1x12 combo. My main amp is a Rivera Jake Studio 1x12 (the direct decendant of the R55-112). I'm familiar with the clean channel on the R-series amps but I never bothered to try the drive channel (Channel 1). Any opinions of channel 1 from the Rivera R-series users out there? Any and all input is appreciated. Thanks!!
