[MOD EDIT].....this thing is ****ing awesome!!! Absurdly punchy. So far the Classic channel, based on a 68 Plexi, is beautiful! Loud as a 100w NMV Marshall can be, but with a top end that reminded me of my JMI AC-30. The Rough channel(Mid 70's MV JMP) is extremely punchy, and it also likes to be played loud. Not a modern metal amp, but if you want the best of what Marshall had offered through out it's 58 years in a single amp, the British Purist might be the one to get.
