The tremolo in the r-12R is a bias modulation type as i recall. The guitar signal never really "goes through" the circuit, The tremolo oscillator just oscillates the bias voltage, much like it does in the fender deluxe.
If you are not getting tremolo, it's possible that the oscillator isn't working. That amp should have a foot switch though, Maybe the foot switch is bad?
