Jupiter Junior Tweed

Discover Koch's Jupiter Junior, a 20-watt guitar combo amp inspired by its predecessor, the renowned Jupiter 45. This vintage-style amp is designed to deliver an authentic, versatile sound experience, perfect for demanding guitarists.

The Jupiter Junior features ATR technology, offering authentic tube response for a rich, nuanced sound. The three distinct channels - Cool, Hot, and Hot Gain Boost - allow musicians to explore a wide range of tones, from crystal-clear tones to more aggressive distortions.

With its spring-loaded reverb system and modulating power, the Jupiter Junior is ideal for rehearsals, studio recordings and live performances. The buffered effects loop and recording output with speaker simulation offer additional options for advanced sound customization.

Compact and lightweight (12 kg), this amp is also convenient to carry, making it the perfect choice for guitarists on the move. The Jensen Falcon C10-40 10-inch speaker guarantees exceptional sound quality, while the optional footswitch offers increased flexibility in channel management.
