Rob Robinette RobRob Deluxe - Lead preset

Verified · 85/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The RobRob Deluxe is Rob Robinette’s two-channel design based on the tweed 5E3 Deluxe. Normal and Lead channels each have their own volume on a 12AY7, sharing the 5E3 tone control, then a 12AX7 gain stage and paraphase inverter with a pre-inverter master volume. A push-pull pair of cathode-biased 6V6GTs runs from a 5Y3 rectifier with protection diodes, plus a three-way feedback/cathode-bypass switch, a 10% power switch and a standby.

• Made in: USA
• Channels: 2

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.
