Orange AD15 preset
Verified · 93/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.
The Orange AD15 is a 15-watt single-channel all-valve amp from Orange's AD series, designed in 1998 when Trace Elliot engineered Orange's amps. One input feeds an ECC83 with a Gain control between its two stages, then a passive treble, middle and bass stack and an ECC83 long-tail-pair inverter with a dual-gang Master after it. Two cathode-biased EL84s run class A without negative feedback from a GZ34 valve rectifier, reaching power-valve breakup at modest volumes.

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.
