I own one. It's one of my favorite amps. I have the 22nd built (which sounds like bragging but really I just like that my serial number is 22 haha). The core tone is the 12,000 series Super Leads and it does that very well. The Modded mode adds gain and a hair of compression but still feels like a Plexi. Just more of a pissed off hot-rodded Plexi. The EQ controls are not your typical Marshall style controls. They have a broader sweep and range to them, especially the mid and treble controls. Also the built in boost circuit works really, really well. It can do a gain boost, volume/solo boost or both depending on how it's set. The effects loop is also excellent. All things told, even with the bells and whistles, it's very simple and intuitive to use. Great amp and George is a great guy to do business with. Currently they're offering a lower gain version of the MP based more around the tones of the 45/100. Email George or talk to Cliff at Destroy All Guitars and see which one would be right for you.
