I use this box for two weeks with a head Marshall 6100 30th anniversary. Warm and powerful at once. Super clean and the crunch channel of the head. Much better than a std box (G12 T 75). It is heavy. Level prices, not cheap but it is the price of a good box, so honest value for money. As against what is right is the power of vintage 30 vs greenbacks with a head 100 W At the moment I'm really not willing to change but it's still early ...
