Koch Jupiter 50 Combo Overview.

The Koch Jupiter is a 50 Watt boutique, vintage style combo amp, which is equally at home in live, recording or rehearsal sessions. This unique tone classic features independent volume and gain controls for both the Clean (Cool) and overdrive (Hot) channels. The overdrive (hot) features a Boost which gives the Jupiter three channels. The shared EQ section (Bass, Middle, Treble) can be further sculpted with the Contour Switch, allowing either a warm, mid-rich vintage tone, or a scooped, more modern and open sound.

The Koch Jupiter 2x12 combo comes with a two button footswitch with another unique feature. The left button switches between the Cool and Hot Channels ,and the right button can be set to turn either the Channel 2 Boost on/off, or the Reverb on/off, allowing you full control over your sound ¦right at your feet!

Further features of the Jupiter include the Dimmer Control which acts as an attenuator to allow you real tube saturated tube tone at any volume, front mounted Reverb control, 4/8/16 Ohm Speaker Outputs and Speaker Emulated Direct Output with Passive Filtering. Finally, there is a buffered effects loop to allow the addition of your favorite pedals or effects units.

The Jupiter was designed as a player's amp, with as much tonal control and flexibility as possible. Even though this is a 2x12 combo. From the bell-like clean tones to the punchy, yet dynamic overdrive channels, the Jupiter delivers pure vintage tone.
