Suprem Super 80 - Channel 1 preset

Verified · 88/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

A 55-watt European tube head: four ECC83s drive two EL34s, with a GZ34 rectifier and an ECC40 modulation circuit labeled Vibrato. Several inputs are mixed through their own volume controls, as in PA-style heads of its time, and the channels share a master (Gesamtlautstärke). It sits in the same family as the vintage German and Swiss EL34 heads of the mid-1960s.

• Made in: Germany
• Wattage: 55W
• Channels: 4
• Preamp tubes: 4× ECC83, 1× ECC40
• Power tubes: 2× EL34

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.
