Silvertone 1344 preset

verified · 86/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Silvertone 1344 is an early Sears combo with three inputs into a 12SJ7 pentode, with Bass, Treble and Volume on a remote upper control panel. A 12SN7 dual triode adds gain and works as a paraphase inverter for two 6V6GT output valves. A vibrato section built on a 12SJ7 oscillator and a 6Y6G has an Intensity control; a 5Y3 rectifies, and the 1550-ohm speaker field coil doubles as the supply choke.

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.
