Mesa Boogie Dual Rectifier - Modern preset

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

The original two-channel Dual Rectifier, built from 1992 to 2000 through revisions C to G, is the Mesa/Boogie that defined 1990s high-gain rock and metal. Orange and Red channels offer Clean, Vintage and Modern voices from five 12AX7s, and a rear switch chooses two 5U4 rectifier valves or silicon diodes, from saggy to tight. Four 6L6s give 100 watts; Revision G (1994 on) moved to a parallel effects loop.

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.
