TONE TALK | The Psychedelic World of Modulation

In the 1940s, the Leslie speaker was invented. It was a cabinet where a drum and horn rotated at different speeds in opposite directions, producing different sounds as the speakers rotated in and out of phase with each other. Attempts to reproduce these sounds resulted in the first modulation effects.

Simply put, modulation effects work by disturbing your clean signals pitch or frequency to create sounds that mimic that of spaceship sounds to vibratos and choruses.



A phaser pedal splits a signal and plays back the two paths at different wavelengths to produce a spacey sound. It has the sweeping effect that guitarists have loved since its creation.


The Flanger is a lot like phaser, but with a wider range of sweeping effect. It has more controls for the guitarist to dial in the sound they want, compared to the more straightforward phaser stomp. Eddie Van Halen used the flanger so much that MXR engineered one just for him and for us to get that signature EVH sound.

Vibrato and Tremolo

Though similar, the vibrato and tremolo are two completely different effects pedals. The Tremolo is a modulation effect that rhythmically changes the volume of your signal to produce a pulsing or shuddering sound. Vibrato is modulation's answer to tremolo; small, fastpitch changes in tone that result in a vibrating sound. Guitars with whammy bars are the manual version of this effect pedal.


Chorus is an effect that splits a signal and then slows and slightly detunes half of it before mixing it back in with the unaffected half. This creates the effect of having two or more guitars being played at the same time. You can hear the chorus pedal shine on the track "Come as You Are" by Nirvana.

Modulation effects produce some of the most interesting and bizarre sounds available for guitar. And in the right hands, one can make a unique sound of your own when you dial in those knobs.
