Verified · 88/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Escort Bass 50 is a 50-watt solid-state bass amplifier from Vox's Escort line. Normal and Bright inputs feed an RC4136 quad op-amp: an input stage with Volume, a Bass and Treble stage, and Harmonics and Middle controls. A discrete power amp follows, with BC212/BC171 and BD537/BD538 drivers and two 2N3055 outputs in quasi-complementary push-pull on a single 80 V rail, capacitor-coupled to the speaker.

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.
