The Marshall brand is not bad, but it is overpriced for a lot of money, not enough music... there is nothing to talk about with Roland, it is a great brand and it is not overpriced, on this and actually on all Marshall combos you will not find any effects or simulations of other combos, maybe a couple effects, it doesn't even have a foot switch, and the quality just screams when you turn it on full blast, but Roland 30 watts doesn't scream, but the game, and the game is beautiful....we only pay for Marshall brand, but not for what's in the combo.
