Silvertone 1335 - Microphone preset

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

The Silvertone 1335 (chassis 185.808) is a Sears two-channel tube combo. Each channel has three instrument-or-mic inputs, its own half of a 12AX7, and its own Bass, Treble and Volume on a remote preamp panel. A second 12AX7 and a 6SN7GT phase inverter drive two 6L6s push-pull, and a 6SJ7 tremolo has Strength and Speed controls with a footswitch. A 5Y3GT rectifies, and a phono-type jack on the chassis gives a further input.

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.
