Echolette BS 40 - Channel 1 preset

Verified · 89/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The BS 40 is an instrument amp head from Echolette, the German company better known for its tape echo units, rated 40 watts continuous (50 W peak). Two channels, each with two inputs, its own ECC808 triode and its own volume, mix into an ECC808 stage with a level control and treble, bass and middle, then an ECC808 paraphase inverter with a presence control drives a pair of EL34s. A silicon bridge supplies the high voltage, with a standby switch.

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.
