Run for the hills my friend,stay well away from the mg series.Hmmm,I can completley recommend a carvin SX300 stack though.I had an SX200 and it ripped.

It blows away any low end marshall.With the new '70/80's in the cabs now,It should be even better.Lots of randall cabs use 70/80's and they charge like twice the price.
