One thing about the bias voltage applied to the output tubes, in a PR... the tremolo/vibrato actually "wags" the negative voltage applied to the signal grid or the 6V6GT's.

Most Fender amps tremolo/vibrato circuits "wag" voltages on the phase inverter input grids.

So, you may see a change in the tone and controls of this EFX, when altering the negative voltage of the bias supply via a pot.
