Watkins Dominator Mk III - Bright preset

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

The Dominator Mk III shares its circuit with the WEM Power Musette Mk II and Dominator Bass Mk I. Two channels each run an ECC83 gain stage into their own Treble and Bass controls, a second triode stage and their own Volume, with a Bright switch on one channel. An ECC83 long-tailed-pair phase inverter drives two EL84s for 15 watts into a 12-ohm output, from a BY127 silicon-diode rectifier.

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.
