ADR Sound Sense Ac301990 preset

Verified · 80/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The ADR Sound Sense AC30 1990 captures the Vox AC30 circuit in its 1990 specification, documenting the amp during the period when Vox production had moved to Korg's oversight following their acquisition of the brand. The 1990 AC30 represents a more refined version of the circuit with improved quality control compared to some earlier transition-era examples. ADR Sound Sense's year-specific reference is valuable for understanding how the AC30 circuit evolved across different ownership and manufacturing periods.

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.
