Tremolo, amplitude modulation of the musical instrument's signal, is one of the oldest electronic effects guitar players have been privy to, as first seen in beloved vintage guitar amps. Vibrato, which in years past was the name mistakenly given to tremolo on many of theses beloved guitar amps, is actually pitch modulation, changing the pitch of your note at a fixed rate.

Electro-Harmonix tremolo and vibrato pedals range from the warm and fuzzy, faithfully recreating the modulation on vintage amps to over-the-top and thoroughly modern giving you classic as well as new sounds for you to discover.
