About KOCH Jupiter 50

Let the Koch Jupiter 50 50W Combo Amplifier with 2x12" Speakers transport you to a world of vintage, boutique-style sound. This 50-watt powerhouse is designed for versatility, making it the perfect companion for live performances, recording sessions, and rehearsals.

The Jupiter features two distinct channels, each with independent volume and gain controls. The Clean (Cool) channel delivers pristine, bell-like tones, while the Overdrive (Hot) channel provides a punchy, dynamic sound. The Overdrive channel also includes a Boost function, effectively giving the Jupiter three separate channels for maximum tonal flexibility.

The shared EQ section, featuring Bass, Middle, and Treble controls, can be further fine-tuned with the Contour Switch. This allows you to effortlessly switch between a warm, mid-rich vintage tone and a scooped, modern sound with an open feel.

The Jupiter 2x12" combo amplifier also comes with a two-button footswitch, offering an additional layer of control. The left button toggles between the Cool and Hot channels, while the right button can be set to either activate the Channel 2 Boost or the Reverb, putting the power of sound manipulation right at your feet.

Additional features of the Jupiter include the Dimmer Control, which acts as an attenuator, allowing you to achieve real tube-saturated tone at any volume. The front-mounted Reverb control, 4/8/16 Ohm Speaker Outputs, and Speaker Emulated Direct Output with Passive Filtering further enhance the Jupiter's functionality.

The Jupiter also includes a buffered effects loop, perfect for integrating your favorite pedals or effects units. Despite its robust 2x12" combo design, the Jupiter maintains a manageable weight of just 31 kg.

Designed as a player's amp, the Koch Jupiter 50 50W Combo Amplifier with 2x12" Speakers offers unparalleled tonal control and flexibility, delivering pure vintage tone from every angle.
