ElectroPlex Rocket 50 preset

Close · 74/100 confidence. Most values readable. Minor gaps filled by inference from similar circuits.

The Rocket 50 is the 50-watt version of the ElectroPlex Rocket. Its drawing shows only the overdrive preamp, shared with the Rocket 100: two inputs feed cascaded triode gain stages with a gain control, a direct-coupled stage into a cathode follower, a Fender-style treble, middle and bass stack and a master, then a long-tailed-pair inverter with an adjustable feedback control to drive a standard Fender-style power amp, plus a line out.

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.
