Ace Tone Rockey A-2S preset

Verified · 90/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Rockey A-2S is a Japanese Ace Tone valve combo from the company that later became Roland. Two Normal inputs and one Treble input feed a single 12AX7 channel with Bass, Treble and Volume. A second 12AX7 drives and recovers a reverb unit with its own level control, and a 6AV6 oscillator gives tremolo with speed and depth plus a footswitch jack. A 12AU7 phase inverter drives two fixed-bias EL84s, with a solid-state rectifier.
