If you want to know what kind of amp tone makes K. K. Rotwang consider turning to crime to possess it, play the video on Hovercraft's page. It's not a "good" promotional video, by Kickstarter standards. The campaign's creator, Nial McGaughey, does not stand before the camera making a heartfelt appeal for money, or cracking jokes about the difficulty of starting an artisanal retro-amp workshop. No sophisticated editing suggests high production values. McGaughey just points the camera at the cliff-face of a Hovercraft half-stack, then lets the forces of tube-driven nature take their course.
That course consists of irradiating you with wide-frequency ionizing tube overdrive until your skeleton glows, causing your flesh to boil away and ignite in a slow-motion doom-cloud that dissolves the objects around you. When you are a luminous skeleton-ghost, held together by bong-resin and infra-bass hypergravity, then your 666th chakra will open, connecting you to the One Riff coterminous with all time, space, birth, and death.
