Description

The Koch J45/C112B Jupiter is a powerful 45W hybrid guitar amplifier combo with an authentic tube sound thanks to Koch's patented ATR (Authentic Tube Response) technology . This technology simulates the characteristic saturation of a tube output stage, while providing the amplifier with solid-state power amplification for reliability and stability. With 2x 12AX7 tubes in the preamp circuit and a custom-designed 12” Koch VG12-90 speaker , the Jupiter delivers a full, rich sound – from crystal-clear clean to sizzling high gain.

The Jupiter features three switchable channels: Clean, Overdrive, and High-Gain Overdrive, each with its own gain and volume controls. The three-band EQ with a contour switch provides additional tone-shaping options. A built-in spring reverb, a buffered effects loop, and a speaker-emulated output make this combo suitable for studio and live recording. A dimmer allows you to adjust the output power for optimal saturation at any volume.
