Epiphone Century 30 (1961) - Channel 2 preset

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

This 1961 tweed Century 30 is a Danelectro-built Epiphone combo. Two channels each have their own 12AX7 triode, bass, treble and volume, mixing into a second 12AX7 whose halves give a gain stage and a split-load phase inverter for a push-pull pair of 6V6GTs. A 6SJ7 phase-shift oscillator, on an octal plug-in, provides tremolo with speed and intensity and a footswitch, and a 6X5 rectifier supplies about 265 V.

• Made in: USA

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.
