Dynacord B 1001 preset

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

The B 1001 is a high-power Dynacord bass and organ amplifier that pairs a transistor preamp board (separate organ, bass and guitar inputs) and reverb with an all-tube output section. Two ECC81s drive four EL34s in push-pull parallel for about 150 W, fed from a solid-state supply, giving the deep, firm low end Dynacord's big bass heads were built for.

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.
