Hughes & Kettner Crunch Master preset

Verified · 82/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Crunch Master (1988) is one of Hughes & Kettner's late-1980s one-watt valve micro amps, built for recording and quiet practice. An NE5532 op-amp front end with a gain control feeds a dual-triode stage with treble, middle and bass, then a master with a bright switch and a single-ended pentode output stage for a speaker. Filtered, speaker-simulated line outputs and a tube-bypass switch let it go straight into a mixer.

Schematic-derived preset files for 16 Fractal and Line 6 modelers: Axe-Fx II/XL/XL+, Axe-Fx III, FM3, FM9, and the full Helix family (Floor, LT, Rack, HX Stomp, HX Stomp XL, Native).

Gridleak extracts amp parameters from original circuit schematics using AI vision — component values, gain staging, tone stack topology, tube types — then generates native preset files for every supported modeler. Every extraction is scored 0–100 and the score is published.
