These pedals are grouped together as "Modulation Effects" for the guitar. These types of effects modulate the audio signal by slowly varying the pitch of the sound. Here is a discussion of each type of guitar foot pedal for modulation effects.


The Chorus pedal produces a doubling effect by playing back a slightly detuned and delayed signal along with your original signal. It is effective when used with a clean amp signal to produce a fuller tone. If you listen to music by The Police, you will hear a lot of chorus effect on the guitar.Here are some examples of Chorus pedals for you to check out:

Electro-Harmonix Nano Clone Chorus Effect Pedal

Danelectro Wasabi Chorus-Trem Pedal


In the "old days", flanger effects were achieved by playing back the same sound on several tape decks while the engineer used his finger to vary the speed of the various tapes.

Fortunately, we now have digital effects which produce a sweeping (somewhat like a jet) sound by setting the delay very short and inverting the signal.

Here are some examples of flanger effects pedals:

Line 6 ToneCore Roto Machine Guitar Effects Pedal

Electro-Harmonix Stereo Electric Mistress Flanger Pedal


The phaser was first created to simulate the sound of the old Hammond B3 organ "Leslie" speaker. This was a giant rotating speaker which had a rotating horn and a spinning drum under a 15-inch woofer.

The sound of a phaser is somewhere between the extremes of the flanger and the sparkling sound of the chorus pedal. If you listen to the first two albums of Van Halen, you will hear a lot of phaser effect on the guitars.

Here are some good phaser pedals:

MXR CSP-101S Custom Shop Script Phase 90 Phaser Pedal

Electro-Harmonix USA Small Stone Phase Shifter Pedal


Tremolo is an effect that was found on guitar amps in the 1950's. The effect was achieved by varying the volume of the signal up and down. With modern digital Tremolo pedals, you can vary the depth and rate of the volume change.

Vibrato is an effect achieved by varying the pitch of the signal. The vibrato effect is heard in the voices of trained singers. If you want to hear the vibrato effect on guitar, listen to Jimi Hendrix and Robin Trower.

Here are some Tremolo and Vibrato pedals:

Boss TR-2 Tremolo Pedal

Electro-Harmonix Micro Pulsar Stereo Tremolo Effects Pedal
