Silvertone 1421 (10XL) preset

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

The Silvertone 1421 is a transistor-era Silvertone combo from the mid-1960s, built by Danelectro as the market transitioned from tube to solid-state designs in the student amplifier segment. Its solid-state circuit produces a brighter, harder-clipping sound compared to the earlier tube models, with a characteristic transistor saturation that some players have found useful for lo-fi and garage rock applications. The 1421 marks the beginning of Silvertone's departure from the all-tube catalog.

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.
