Re: Y'know the Marshall MG series...?
I'd go with a digital amp if you want solid state, IMO the avt's are crap too. Even for solid state amps. Really, you could get a good used smaller tube combo for almost less than you could a new AVT.
But to answer the thread, they don't sound like marshals at all. I think they just sound like every other entry solid state amp marketed to beginners who want famous brands at modest prices. Lol, last time i went into a guitar store this kid who couldnt have been more than 14 had just got a Ibanez tone blaster 100. I wish i stopped him.
