This amp has a xlr input. It's powerful. It's tube. Yet nobody is talking about it. The more I explore amplification the more I see that there is a lot out there. What would keep me, or anyone, from running a Headway Pre with my AMT + Gage pick up, into this with a ACME B1 or Thunderchild and just kick ass? Does anyone have this combo? What about a Aguilar ToneHammer 500? I've got the QSC K10 which I think is cool but not quite enough for a full drum kit gig.
