Harmony H530 preset

Verified · 88/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The H530 is an all-transistor Harmony combo from the company's solid-state era, sold as an affordable companion to its guitars. Three inputs feed a two-transistor preamp with volume and tone controls, then a differential stage and driver into two 2N3055 output transistors on split 30-volt rails. It drives a 15-inch 8-ohm speaker, with an extension speaker jack. Clean, firm and loud rather than tube-like in breakup.

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.
