Koch Jupiter 45 Combo

The Koch Jupiter 45 Combo is a powerful 45-watt boutique amplifier, perfectly suited for live gigs, studio recording, and rehearsals.
Featuring classic vintage-style tone and advanced ATR (Authentic Tube Response) technology, the Jupiter delivers true tube feel and maximum tonal flexibility.

The amp offers three footswitchable channels: Cool (clean), Hot (overdrive), and Hot Gain Boost.

• Cool channel delivers pristine bell-like cleans.

• Hot channel offers punchy yet dynamic overdrive, perfect for vintage rock tones.

• Hot Gain Boost provides additional saturation for heavier rock sounds.

Both the Clean and Hot channels have independent volume and gain controls.
The shared 3-band EQ section is further enhanced by a Contour Switch, allowing either warm, mid-rich vintage voicing or a scooped, modern tone.

Other features include:

• Dimmer Control acting as an attenuator for saturated tone at low volumes.

• Buffered effects loop for optimal pedal integration.

• Speaker Emulated Output for direct recording or live FOH connection.

• 4/8/16 Ohm speaker outputs for flexible cabinet matching.

• Built-in spring-type reverb with front-mounted control.

A two-button footswitch is included, with one button switching channels and the second programmable for either gain boost or reverb.

The Koch Jupiter 45 Combo is designed for serious players seeking total tonal control and classic tube warmth in a compact format.
