Dynacord Twen preset

Verified · 90/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Twen is a small 1967 Dynacord combo. Two inputs of different sensitivity feed an ECC83 gain stage, then a volume (Lautstärke) and a tone (Klang) control, a second gain stage and a cathodyne phase inverter driving a push-pull pair of cathode-biased 6V6s. A second ECC83 runs a phase-shift tremolo with speed (Frequenz) and depth (Amplitude) controls and a footswitch jack, and an EZ81 valve rectifier supplies it.

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.
