With the plethora of guitar amps developed over the last seven decades, as well as the emergence of digital modeling technology that makes most of those amps’ tones available for pennies on the dollar, the best strategy for any company designing a new amp is to offer significant improvements or new tones unlike any product ever offered before. 

RedSeven has accomplished both of these feats with their formidable Leviathan amp head, a 120-watt two-channel beast that produces some of the most aggressive high-gain tones known to mankind.
