Ceriatone Prinzetone Ultra preset

Verified · 85/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Prinzetone Ultra is Ceriatone's blackface Princeton-style amp. A single input runs two ECC83s through volume, treble and bass, with a Boost switch that lifts the tone stack for extra gain, and tube tremolo with speed and intensity plus a footswitch jack. Two 6V6GTs with an adjustable bias run from a GZ34 rectifier, with a variable negative-feedback control. It gives the small-Fender clean with more push when needed.
