Premier Twin-8 preset

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

The Premier Twin-8 is a small tube combo with two 8-inch speakers from the New York Premier (Sorkin/Multivox) line, built from about 1959 into the mid-1960s. Instrument and mic inputs feed a 12AX7 gain stage, a Tone control and Volume, and a second gain stage driving a single-ended output valve: a 6V6GT in early 1959-60 sets and a 7591A in the 1961 and 1964 versions. A second 12AX7 provides footswitchable tremolo, with a speed control on later versions.

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.
