I break the KSR Mold as I'm not a high gain guy but its nice having it on tap.
Rhythm channel, Ares crunch mode, bright switch down, feel middle is unreal with single coils. I just adjust the gain to taste and I'm in business. I can go really bluesy but its never flubby or muddy.
I'm building an entire small board around the Ceres for direct to FOH settings (I do a lot of theater work). Stick the Ceres in front of your favorite IR box and run direct to the sound guy. Its perfect.
The clean channel, however, is the unsung hero. Spanky, tight, with a sweetness to it.. very smooth.
I haven't used the lead channel much... I'm not really a lead player. But the tones I coaxed out of it would certainly be useful for people that are looking for that.
