Electric guitar combo amp
The Koch Jupiter Junior is a 20 Watt boutique, vintage style combo amp based on his bigger brother the "Jupiter 45". Driven by two 12AX7 tubes, split between the power amp and pre-amp sections, the Jupiter Junior is a flexible hybrid amplifier. Using Koch's ATR (Authentic Tube Response) technology, the rest of the solid-state circuit simulates the feel of a full-fledged tube amp.
