About KOCH Jupiter 45

You'll discover the Koch Jupiter 45 45W Guitar Amplifier Head, a boutique-style, vintage-inspired powerhouse that's perfect for live performances, recording sessions, or rehearsals. This unique, tone-rich classic offers independent volume and gain controls for both its Clean (Cool) and Overdrive (Hot) channels, providing you with a wide range of sound customization options.

The Overdrive channel boasts a Boost feature, transforming the Jupiter into a versatile three-channel amplifier. The shared EQ section, complete with Bass, Middle, and Treble controls, can be further fine-tuned with the Contour Switch. This allows you to achieve either a warm, mid-rich vintage tone or a scooped, modern, and open sound, depending on your musical preference.

The Koch Jupiter Amplifier Head comes equipped with a two-button footswitch, offering another unique feature for your convenience. The left button allows you to effortlessly switch between the Cool and Hot channels, while the right button can be set to toggle either the Channel 2 Boost or the Reverb on/off. This gives you complete control over your sound, right at your feet.

Further enhancing its versatility, the Jupiter includes a Dimmer Control, acting as an attenuator to deliver real tube-saturated tone at any volume. It also features a front-mounted Reverb control, 4, 8, and 16 Ohm Speaker Outputs, and a Speaker-emulated Direct Output with Passive Filtering.

To top it all off, this amplifier head includes a buffered effects loop, allowing you to add your favorite pedals or effects units seamlessly. Designed as a player's amp, the Jupiter offers maximum tonal control and flexibility in a compact, lightweight head. From bell-like clean tones to punchy, dynamic overdrive channels, the Jupiter is your key to unlocking pure vintage tone.
