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

The Vox AC30 is one of the most influential amplifiers in rock history. Running four EL84 tubes in Class A, it produces warm compression, harmonic bloom, and the unmistakable British chime and jangle. Originally designed for Hank Marvin, adopted by The Beatles, The Edge, Brian May, and countless others. The Normal and Top Boost channels define the AC30's sonic identity.
