Rob Robinette RR763 BlackVibe 6V6 preset

Verified · 95/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The RR763V BlackVibe 6V6 is the 6V6GT version of Rob Robinette’s single-channel design based on the blackface AB763 Vibroverb, with no reverb or tremolo. High and low inputs feed a 12AX7 stage, a blackface treble/bass/mid stack and volume with a bright switch, then a second 12AX7 stage. A 12AT7 long-tail inverter drives two fixed-bias 6V6GTs with adjustable bias, a GZ34 rectifier with backup diodes and a standby switch. It makes about 14 watts.

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.
