Feature:
Footswitch is awesome. I have always wanted an amp that had a solo switch to increase my solo volume when necessary. PREFECT! The reverb is independent of amp 1 and amp 2 so you can vary your reverb amp to amp. Reverb sounds fantasic on this amp

Value:
Expensive but worth it. I only wish the cabinets were less expensive. I haven't purchased the mf400a cabinet yet but I plan to because I am using an older peavy for now.

Desirability:
It's a marshall...enough said. This is a very subtle but aggressive change for marshall. The look of the amp is all business.

Sound:
Gave it a 9 on this because the only thing about the amp that is disappointing is that if you switch between clean and crunch you may experience an unexpected volume increase. In the manual they discuss the "sweet spot" between these two channels. This makes things difficult but you can dial it in to where this isn't a huge problem. Just be aware of it.

Support:
Never dealt with them.

Overall:
I have owned counless stacks from Peavy supreme, 5150, crate and this marshall is by far the best and most versatile out of any amp I have owned or played. If you want a rockin' amp this is the one. You can easily add a few stomp boxes to complete your rig and have an excellent sound without any rack effects.
