Laney AOR 50 Series II - AOR preset

Verified · 90/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Laney AOR 50 Series II is the 1989 50-watt head of Laney's revised AOR range, drawn as the A50 Series II. High and low inputs feed AOR Gain and Preamp Volume into cascaded ECC83 stages, then a treble, middle and bass stack with Mid Boost and Bass Boost. Normal and AOR channels each have their own master with a Top switch, and an op-amp effects loop, line out and Presence lead to a pair of EL34s.

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.
