General
The Koch Jupiter and the Koch Startrooper are in a league of their own in among hybrid guitar combos. Both are both fitted with a 12AX7 tube, combined with special ATR (Authentic Tube Response) technology, that allow the sound to come surprisingly close to a full-valve amplifier. Additionally, you can draw a wide range of timbres from the vintage-sounding Jupiter.
Jupiter: From Cool to Hot
The Jupiter features two channels, each with its own gain and volume control. The footswitch toggles between the clean (Cool) and overdrive (Hot) channel. Use the right knob to apply boost or reverb. Very practical features of this amplifier combo are its dimmer (for full-fledged overdrives at low volumes) and its two speaker outputs (which allow you to connect one or two 16-Ohm, one or two 8-Ohm or a single 4-ohm speaker). Lastly, the 3-band EQ allows you to go from a warm vintage sound to more modern, open tones.
Koch Quality
After years and years of being a guitarist and valve-amp expert, the Dutch Dolf Koch started his own business in 1988. The brand's high-quality guitar and bass guitar amplifiers are practical and versatile, and have a unique balanced sound. All of them are carefully crafted and tested, which is why many professional players rely on Koch quality!
