Westbury 10005M Bass preset

Verified · 80/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Westbury 10005M Bass is the master-volume-equipped variant of the 10005 Bass, adding a master volume control for independent gain and output level adjustment. This feature allowed bass players to set a consistent input gain while adjusting overall stage volume, which was a practical advantage for live performance. The 10005M is otherwise functionally identical to the standard 10005 Bass.

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.
