Tremolo

Tremolo pedals are effects pedals that are used to produce a fluctuating or pulsating sound by rapidly and repeatedly turning the volume of the input signal up and down. They are often used to create a sense of movement or depth in the music, and are commonly associated with surf rock and blues music.

Tremolo pedals work by using a low-frequency oscillator (LFO) to modulate the volume of the input signal. They typically feature a range of controls, such as depth, rate, and waveform, that allow the user to shape the sound of the pedal to achieve the desired effect.

Some popular examples of tremolo pedals include the Fender Tre-Verb, the Boss TR-2, and the Electro-Harmonix Stereo Pulsar.
