About KOCH Jupiter 45

Explore the world of superior sound with the Koch Jupiter 45 45W Combo Amplifier, a boutique-style amplifier that boasts a vintage aesthetic. This 1x12" speaker combo amp is designed to deliver exceptional performance in live shows, recording studios, and rehearsal sessions, making it a versatile addition to any musician's gear.

The Koch Jupiter 45 is a three-channel amplifier, offering independent volume and gain controls for both the Clean (Cool) and Overdrive (Hot) channels. The Overdrive channel features a Boost function, adding an extra layer of versatility and control to your sound.

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

The Jupiter 45 combo amp comes with a two-button footswitch, offering a unique feature that allows you to switch between the Cool and Hot channels with ease. The right button can be set to turn either the Channel 2 Boost or the Reverb on/off, giving you full control over your sound 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 flexibility and control of your sound.

The Jupiter also includes a buffered effects loop, perfect for integrating your favorite pedals or effects units. Designed as a player's amp, the Jupiter 45 offers an impressive amount of tonal control and flexibility in a compact, lightweight combo. From bell-like clean tones to punchy, dynamic overdrive channels, the Koch Jupiter 45 45W Combo Amplifier delivers pure vintage tone in every setting.
