this is that 4 channel solid state that costs as much as a mesa right?
send it back to hell where it came from. The thing IS solid state whatever they say to the contrary, it has a few lonely preamp tubes that are suppose to help the sound and thats it. Basically what you get is a souped up valvestate with 4 channels and a massive price tag that no one in their right mind would pay. If I understand the reasoning behind Marshall (but who does these days) the amp is really meant to hook all the nu-metal guys that don't know any better. In other words it gives muddy tone with tons of low end and tons of SS gain (that sounds nothing like tube gain).
Does it compare to a "real" marshall or mesa? I very much doubt it. There are a few amps that get pretty close to tube tone without using tubes but the valvestate series doesn't even try. There is no way in hell this thing pumps out the same sound as a DSL 2000 or a Duel Recto...and for that matter a laney or a peavey.
Just buy a 5150 and save yourself the trouble. Want the best reason? In Flames, Arch Enemy, Children of Bodom, Soilwork....the list goes on. Another option is also a Laney, GH or VH series. That is what I personally use and believe me....they are great for death metal. Either of those options will give what you want without spending far too much money on a substandard amp.
