General

The 45 Watt 45-H is the Head-formatted version of the Koch Jupiter guitar combo. This hybrid boutique amp is driven by a pre and power-amp loaded with 12AX7 tubes and steered by the capable of hand of Koch's very own Authentic Tube Response technology. The result is full-grown and fat tube-sound, all wrapped in a little vintage suitcase-styled housing, keeping it lightweight and considerately priced. Since the Jupiter Head pushes a relatively conservative 45 Watts of power, it can serve during home rehearsals, studio sessions as well as on stage as part of a rig while two built-in reverb effects and a boost function on the second channel support dynamic tone.

The Koch Jupiter Head: From Very Cool to Piping Hot

The Jupiter Head has two boutique-grade channels: a Cool clean channel, and growling Hot channel. Both have dedicated volume and gain controls and can be remotely switched using the included two-button footswitch. A shared three-band equaliser takes care of the overall colouring and is backed up by a contour switch able to create a more modern, scooped sound. The master section offers a classic spring-style reverb and a stepless 100 to 0% power dimming pot that maintains that sweet tube-style rip and compression at lower volumes.

Koch Quality

After a long career as a guitarist and tube amp expert, Dolf Koch founded his own company in 1988. Ever since, the brand has been steadily developing high-quality guitar and bass amplifiers that focus on practicality, versatility and the delivery of a balanced, unique sound. Since each amp is carefully constructed and diligently tested in great detail, it's little wonder that so many professionals rely on Koch quality!

Wrote the following about Koch Jupiter Head 45W Hybrid Guitar Amplifier Head

Prachtig afgewerkte head, zoals ie eruit ziet bezorgt ie dan ook een kwalitatief, warm vintage geluid met veel (hybride) buizenkarakter, met 45w meer dan voldoende headroom, sparkle en volume. Eenmaal een goed geluid geluid ingesteld behoud je dit met de 'dimmer' functie prima op lagere volumes.

Het hot kanaal klinkt prima, britisch, crunch, bluesy.. maar het cleane (cool) kanaal is is voor mij de absolute uitblinker, en gaat prima samen met pedaal gebruik.

Met de verschillende output impedantie mogelijkheden kun je alle kanten op qua speakercabinet combinaties. Met 2 palmer cabinets geladen met resp celestion vintage 30 en celestion creamback helemaal.. top!
