Tremolo:  Tremolo is a modulation effect that rhythmically changes the volume of your signal.  The end result is like someone turning the volume up and down quickly.

A LFO (low frequency oscillator) is used to create a waveform that is used to turn the signal up and down.  The classic tremolo effects are usually made with sine or triangle waves. Sine waves are rounded waveforms that provide a lush, strong tremolo, while a triangle wave, with its straight, linear rise and fall, creates peaks and valleys that can command attention and cut through a mix.

Whenever you see tremolo in an amp or a pedal, you will normally have at least two controls; “Rate or Speed” and “Depth or Intensity”. Rate lets us sync the effect to the tempo of our song, while Depth sets the limit of volume loss of the effect, from subtle variation to completely deadening the signal.

Simpler Definition:  Sounds like someone turning the volume up and down repeatedly.
