Ceriatone Rock-It preset

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

The Rock-It is a Ceriatone head in the Trainwreck EL84 mould. Two 12AX7 gain stages feed a volume, treble and bass, then a cut control ahead of a 12AX7 long-tail phase inverter, with no master and no negative feedback. Four cathode-biased EL84s run from a GZ34 rectifier, with an HT select switch for a softer or firmer supply, a half-power switch and an impedance selector. It gives a raw, chimey, touch-sensitive EL84 crunch.
