WEM Westminster Mk IX preset

verified · 91/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Westminster Mk IX is a 1973 version of the Watkins/WEM Westminster small combo, rated 10 watts RMS into 12 ohms. Two inputs feed half an ECC83, a Bass and Treble network, the second ECC83 half and a Volume. The triode halves of two ECL82s form a cathode-coupled phase splitter driving their pentode halves in push-pull, cathode-biased with negative feedback, from a two-diode BY127 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.
