ADR Sound Sense Ac301989 preset

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

The ADR Sound Sense AC30 1989 documents the Vox AC30 circuit in its 1989 form, capturing the specific component values and topology of the amp at that point in its production history. The AC30's chimey, compressed EL84 tone and top-boost circuit have remained foundational to British amplifier sound since the amp's introduction in 1960. ADR Sound Sense's year-specific documentation acknowledges the subtle differences between AC30 production eras.

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.
