Selmer Little Giant Mk III preset

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

The Little Giant Mk III is a later revision of Selmer’s small single-ended practice amp. A single input feeds one ECC83 triode, then 1M Tone and Volume controls and the second triode, which drives one cathode-biased EL84 in Class A into a 3 ohm speaker, with no negative feedback and an EZ80 rectifier. The simple layout gives a warm, compressed tone at low volume.

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.
