Got it in the mail today and plugged it into my 8" PPC108 Orange cab and even with the gain cranked and messing with the tone and volume I was getting no crunch just big fat clean tones which sound great.,but not what I'm looking for.So then I put it in a 2x12 with V30s and same result no crunch no hi gain metal tones nothin like that.Whats goin on with this supposedly hi gain box of metal death?
Yeah, obviously something is not right here.  Were you able to figure it out?  Were all of the cables plugged into the correct connections?

This might sound silly, but have you tried a different guitar lead.  9 times out of 10 any problem in the signal chain will be leads rather than anything else
