Blended from circuit-archetype lineage, dynamic feel, tone-signal overlap and tone-vector distance — the tone vector itself is derived from editorial description text, not a measured acoustic signal, so this reflects how similarly the catalog copy describes the two, not a lab measurement. Shown only within a gear class, and only where there's enough evidence to be meaningful.56% — moderately similar

The Koch ST20/H is a 20-watt head from the Dutch boutique maker, known for building amplifiers with switchable power stages allowing different tube configurations from a single chassis. The ST designation places it within Koch's catalogue separately from the Classictone line. Independent coverage of this specific model outside Europe is limited, so this description does not assert its channel count, voicing or tube complement beyond what the model name establishes.
The Morgan Dual 20 is a two-channel 20-watt 1x12 valve combo, and the two-channel layout is what separates it from the single-voice amps that make up most of the Morgan range. That lets it hold a clean and a driven sound rather than relying on the guitar volume to move between them. Morgan build hand-wired in small numbers in the United States. It suits players who want boutique valve tone with genuine channel switching at room-friendly wattage.
