Blackstar Artisan 15H - Channel 2 preset

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

The Artisan 15H is a hand-wired 15-watt head from Blackstar's Artisan boutique line. It has two channels, each with high and low inputs, a volume and a single tone control: Channel 1 is a single 12AX7 triode stage, while Channel 2 adds a 6267 (EF86) pentode for a thicker, hotter voice. Each channel drives one side of a 12AX7 inverter into two cathode-biased EL84s with a 5 W / 15 W switch, on an EZ80 tube rectifier.

Schematic-derived preset files for the Neural DSP Quad Cortex and 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.
