Koch Amps debuted two affordable new hybrid amps that feature 12AX7-driven preamps, solid-state power sections, two EQ-sharing channels, and a boost function. The Jupiter has a 12" Jensen speaker with a neodymium magnet and is voiced for blues and rock tones. The Startrooper (not pictured) is voiced for higher-gain tones and features a custom Koch 12" speaker modeled after a Celestion Vintage 30. Both sounded remarkably tube-like from the floor of the show. koch-amps.com
