Vox AC30CC2 - Normal preset

Verified · 92/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Vox AC30 is arguably the most recorded amplifier in the history of rock — four EL84s in cathode bias, no negative feedback, and a Top Boost channel that produces a chiming, bell-like clarity at low volumes and a singing, compressed overdrive as the output stage saturates. The Beatles ran them wall-to-wall through every stage and studio session of the early 1960s, establishing a sonic palette that defined British Invasion guitar. The Edge's metronomic delays on U2's 1980s records, Brian May's multilayered orchestrations on Queen albums, and Radiohead's fragile clean tones all run through AC30 Top Boost channels. The 2005 Custom Classic service manual covers a production era when Korg-supervised Chinese manufacturing kept the essential circuit intact while making the platform accessible — the same two channels, the same EL84 cathode-bias power section, the same irreplaceable sound.
