I haven't delved into the middle long, but all the way down does great 70's to 80's rock.
I'm in the up position highest gain, boosted and gain backed down. Very aggressive. It's almost like a Splawn's Gear 1 and Gear 2. But, of course the voicing is much more high-mid focused, closer to a traditional Marshall vs. Scott's flavor.
I don't use the sat switch. Its fuller, bigger, and the sat thins it out. It's much bigger, and still aggressive with it off and boosted.
