Silvertone 1392 - Microphone preset

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

The Silvertone 1392 is a Danelectro-built tube amp from the late 1950s. It has two channels with separate volume controls and a shared tone control. Tremolo comes from a 6AU6 oscillator with speed, intensity and a footswitch. Two 12AX7As drive a push-pull pair of 6V6GTs into a 12-inch speaker, on a 6X5 rectifier.

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.
