Vox AC30/6 Normal (1960) - Brilliant preset

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

The AC30/6 Normal of 1960 is the early AC30 before Top Boost. Bright, Normal and Vib/Trem channels each have high and low inputs and their own volume; Bright and Normal share an ECC83, Vib/Trem has its own, and an ECC83 oscillator with ECC82 modulator gives vibrato or tremolo (Speed, Depth preset, footswitch). An ECC83 long-tailed pair with tone cut drives four cathode-biased EL84s with no feedback, on a GZ34 rectifier.

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.
