The term 'Tremolo' refers to a rapid and continuous change in volume and is a popular guitar technique used to create a wavering or vibrating sound. It can be compared to a spotlight that alternates between brighter and dimmer intervals at short time intervals. One way to achieve this effect would be to quickly turn the volume knob up and down on an amplifier. However, since both hands are needed for playing the guitar and manually adjusting a knob this fast and consistently would be impossible, guitarists typically use dedicated tremolo effect pedals to generate the effect automatically. Most of these pedals offer adjustable depth (the desired difference between the softest and loudest point of the tremolo effect) and effect speed.
A Vibrato works similarly to a tremolo effect but modulates the pitch instead of the volume. This gives the note a "wobbling" or "shimmering" effect, which is typically perceived as more emotional and expressive, as singers often create vibrato naturally with their voices. Guitarists achieve vibrato in two ways: as a playing technique, by quickly bending the string back and forth while fretting, or by using a dedicated vibrato effect pedal.
A Rotary effect is a guitar effects unit that modulates sound as if it is spinning around the listener. This effect emulates the sound of classic Leslie speakers, which were originally designed for Hammond organs. The rotating speaker produced a unique, spacious sound. Modern rotary effects can now replicate this tone with much smaller and more practical equipment. These effects are commonly found in pedal form or as digital effects and can be used across various music genres to add a distinctive spatial dimension to the sound.
