Ceriatone AFD 35 50W preset

Verified · 84/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

Ceriatone's AFD #35 50W is the 50-watt version of its Appetite for Destruction-inspired head. Four ECC83s cascade gain into a cathode-follower tone stack and long-tail inverter driving two 6550s on a solid-state rectifier. A footswitched relay picks Gain 1 or Gain 2; controls are a three-way bright switch, bass, middle, treble, presence, master and a post-PI master, plus an effects loop and a pentode/triode (50/25 W) 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.
