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

The Alamo Paragon Special is a two-channel tube amp from Alamo Electronics of San Antonio, Texas, with Normal and Bass channels. Each channel has two inputs, a 12AX7 stage, its own Treble and Bass, a second gain stage and its own Volume. The channels mix into a 7199 driver and phase inverter feeding a push-pull pair of cathode-biased 5881s, with a 5U4 rectifier, standby switch and extension speaker jack. No tremolo is drawn.

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.
