Series 60 is the second amp from AcmeBarGig's "Preampus Metal Line" of heads. As the name suggests, these amps are for the Metal Heads amongst us.
About Series 60, AcmeBarGig's says: "Series 60 is Power defined. Inspired by the power plants that drive America today, it is the most powerful amp we've ever produced here at AcmeBarGig, and we actually set out to make it equivalent to an 8,000 watt amplifier, so believe us when we say there's enough power in this amp to make your skull crumble and your toes go numb. Add in the fact series 60 comes with a built-in Drive Amp and you have some scary potential for gain, the Death Metallers out there should LOVE the Series 60."
