I think that they are the best sounding marshall in the jcm 2000 range as far as tone. I had bought one new when they came out for $600 and it worked well for about 2 yrs, then the volume would drop or fade in and out after about 20 minutes of use. I retubed it and had a tech look at it an fix it, about a week later the issue returned, an it was getting expensive so I sold it as is. THey run very hot which I think causes poor solder joints on the board to fail etc. I have heard from some that marshall fixed these problems in the later run but I am not sure. I would like to have one if it worked and wasnt a lemon because the portability and decent tones for that price is a decent deal.
