Koch Jupiter Junior J20C Combo

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.This means that you can attain that genuine tube sound but at a great, affordable price. And the use of only 2 tubes also minimises the chance of failure, meaning that the Jupiter Junior is a very reliable amp that is ideal for small to medium-sized club gigs with its 20W of power.
