Koch Amps Jupiter 45W 1x12 combo

A Boutique Amp with Vintage Tones


The Jupiter amp packs excellent versatility and amazing tonal selection into one lightweight, robust combo amp. It projects a classic, vintage tone thanks to 45W – making it more than comfortable in practice sessions, studio recording and live scenarios. Choose from cleaner sound with brilliant clarity, or tweak the intuitive overdrive channels and receive much more punch in return!

Vintage Style & Tone

Koch have developed a boutique amp that boasts a bunch of options which are sure to improve both your sound and levels of creativity. The vintage tone boasts dedicated gain and volume controls for the overdrive and clean channels, while the overdrive also features an additional boost option. You can then tweak your tone even further using the contour switch to craft the shared EQ section. This allows you to achieve a more modern, scooped sound or a warmer, rich vintage one.

Two Button Footswitch

A unique two button footswitch comes bundled together with the Jupiter. Use the left button to swap between the hot (overdrive) and cool (clean) channels on the fly, or activate the right button to switch on or off the channel 2 reverb and boost.

Additional Features

A number of extra features enhance the Jupiter’s flexibility even further. Add your preferred effects units and pedals to proceedings using the buffered effects loop; utilise the dimmer control to achieve a brilliant tube saturated sound at any volume; experiment with the spring style reverb with a front mounted control. The creative options available here are extremely widespread.
