Harmonic Tremolo

Harmonic Tremolo

The Harmonic Tremolo effect in the Fender Tone Master Pro emulates the classic harmonic tremolo circuits found in vintage Fender amplifiers, particularly from the early 1960s. This effect splits the signal into high and low frequencies, modulating them in opposite phases to create a lush, swirling tremolo with a unique sense of movement and depth. It delivers a warm, musical modulation that stands out from standard amplitude tremolos, offering a rich, three-dimensional character ideal for both subtle texture and pronounced rhythmic effects.
