haha! clean is excellent, crunch is excellent, rhythm excellent , and hi gain lead killer. It's a very versatile amp , really does alot of great tones. The z10 footswitch is killer because i have it setup so when i go to a lead it switches the amp to SMOOTH mode from rough mode (which is what i use for rhyhms) and switches from master a to master b , and switches from presence a to presence b, so i can really dial in a really cool lead tone.
