That's one of the factors I was alluding to above, matter of fact, Fender once released a different kind of Tremelo effect in one of their amps, that not only changed the Amplitude of the signal repetitively, which is the classical definition of Tremelo, but also varied the PITCH very slightly in accordance with the pulse of the oscillator at the same time.
