Randall RG100ES / RG80ES - Ch 1 preset

Verified · 80/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Randall RG100ES and RG80ES are solid-state guitar amplifiers from Randall's legendary RG series, producing the tight, uncompressed high-gain tones that made the brand famous in 1980s and 1990s metal. Their solid-state design delivers consistent, articulate distortion with a hard-hitting low end that cut through in the era's dense mix environments. The RG series became iconic largely through Dimebag Darrell's use of these amps in Pantera, defining a generation of metal guitar tone.

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.
