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.44% — somewhat different

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 Marshall 1959JMH is a limited-edition hand-wired version of the 1959 Super Lead 100-watt Plexi, built to vintage specification with point-to-point wiring and EL34 power valves. Like the original Super Lead, it has no master volume, so its big, open cleans turn to rich, saturated crunch only when the power section is driven hard. Four inputs and two jumperable channels deliver the classic British stack voicing heard across late-1960s and 1970s rock.
