I tried this when it was 'happy'... did somebody say LOUD!!!! a V8 is supposed to be more (a bit) at 400W, had two V8s, they do what they do but not at this volume.. if you've got the cabs I'd deffo get Marshall to have a look.. it's odd, it's physically big and 'feels' well...'dangerous'... or was that yahoo, bring it on... not recommended for bedroom use
