Ceriatone Champ Ultra preset

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

The Champ Ultra is Ceriatone's expanded take on the single-ended Fender Champ: two ECC83s feed a single 6V6GT in class A, on a 5Y3 rectifier. Where the original has only volume, it adds bass and treble controls with a boost switch that lifts the tone stack out of the circuit, plus tremolo with speed and intensity and a footswitch jack. An impedance selector rounds it out, for small-amp tones at recording and home levels.
