Hughes & Kettner Hk Crunchmachine preset
Verified · 80/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.
The Hughes & Kettner Crunch Machine is a single-channel all-tube head optimized for aggressive crunch tones at lower gain settings. Its EL84-powered output stage gives it a distinctive chime-with-grind character reminiscent of British combo amps. A simple control set — volume, bass, middle, treble, and gain — keeps the focus on expressive playing dynamics.
