Dynacord Jazz - Channel 2 preset

Verified · 92/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Jazz is a simple Dynacord EL84 amp from about 1961. One ECC83 gives each of the two inputs its own triode and volume control (plus a bridged third input). A single tone control follows, then a second ECC83 provides a gain stage and cathodyne inverter for two EL84s on a shared cathode resistor, with an EZ81 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.
