Futurama Caravelle preset

verified · 82/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Caravelle is a 15-watt valve combo from Selmer's budget Futurama range of the mid-1960s, built on a printed circuit board to keep costs down. Two channels, each with a pair of inputs and its own volume and tone, run on an ECC82 and mix into an ECC83, whose other half is a phase-shift tremolo with speed and amplitude controls. An ECC82 cathode-coupled inverter drives a push-pull pair of 6BW6s on an EZ81 rectifier.

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.
