Morgan DAG15C preset

Verified · 94/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The DAG15C is a single-channel valve combo from Morgan Amplification, an American boutique builder. One input feeds half a 12AX7 (the other half unused), a Volume with a bright switch, then two more gain stages into a Treble and Bass stack. A 12AX7 long-tail phase inverter with a Vox-style Cut control drives two cathode-biased EL84s with no global feedback, from an EZ81 rectifier, with a MOSFET Output Level control that scales the power.

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.
