KISS guitarist Tommy Thayer found the amp he had been seeking in the Hughes & Kettner Duotone. His signature and official KISS logo now adorn the glowing blue front panel. Both the amp and the matching Signature Edition CC 412 A30 SE Cabinet come with a highest-quality faux croc leather covering. Tommy donates his royalties from the sales of the signature model to the Los Angeles Children's Hospital. The hospital invests the proceeds in an in-house music therapy program.
