This amp is also known as the Crate V50. I've never actually seen or played on one, but from youtube its seems this amp has a brilliant clean channel with lots of head room and lots of chime coming from the 6L6 tubes... quite difficult to distort. The Dist/OD channel is said to be voiced somewhat dark or weird I duno :-\ but seems it will give a nice blues tone if you back the gain a bit down. Some say its sounds better with a pedal to drive the OD channel than to use the actual amps dist if you want to get that rock sound.
