ADA Rocket RA-10 / RA-20 preset

Verified · 84/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The ADA Rocket RA-10 is a compact single-ended tube amp: one 12AX7 feeds a treble/bass tone stack and volume with bright switch, then a cathode-biased EL84. A Gain Boost switch bypasses the second stage's cathode and a 'Power Amp Thrust' switch changes the negative feedback. The RA-20 is the larger version of the same design.

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.
