Epiphone Electar Zephyr (1949) preset

Verified · 85/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

This late-1940s Epiphone Electar Zephyr was built for Epiphone by Danelectro, before Gibson bought Epiphone. Two versions exist. The tremolo version has instrument and mic inputs with their own volumes, a 5879 pentode preamp, a 6SL7GT driver and inverter, and a 6SF5GT tremolo oscillator. The later version has three inputs, volume and tone, and three 6SJ7 pentodes, with the speaker field coil as the filter choke. Both drive a pair of 6L6Gs on a 5U4G rectifier with no negative feedback.

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.
