Westbury 1005M Bass preset

Verified · 85/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Westbury Model 1005M is a variant of the Unicord-era 1005 solid-state bass amp. Two inputs feed a K117 JFET stage, a passive Bass, Treble and Middle network and a Volume with a Bright switch, then further JFET gain stages. A discrete power amp with D845/B755 complementary outputs runs on a single 68 V rail into a 4-ohm speaker; the drawing shows no line out or extension jack.

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.
