Guitar foot pedals come in all shapes and sizes and what I have done on this page is show you using youtube clips what each pedal sounds like and what it does to the guitar sound. Then you can make a decision on which pedal to buy to fit your particular sound.
The Wah-wah Pedal
This pedal has been used on many famous guitar solos, such as on Cream's "White Room", Jimi Hendrix's "Voodoo Child (Slight Return)", the Guns N' Roses hit "Sweet Child o' Mine", Pearl Jam's "Alive", Jethro Tull's "We Used to Know", Drowning Pool's "Tear Away", Metallica's "Enter Sandman" and U2's "The Fly".
Distortion/Overdrive Pedal
The use of distortion came about by accident in which the guitar amplifier was in some way damaged, but the player or producer decided they liked it and recorded it that way.
The earliest uses of intentional distortion that have been recorded were achieved through "doctoring" amplifiers and speakers. Guitarists would use a razor blade, screwdriver or pencil to poke holes into their speaker cones to create a distorted sound.
Fuzz Pedal
Nashville session musician Grady Martin discovered the fuzz sound in 1961 during a recording session for Marty Robbins' "Don't Worry", due to a faulty recording console preamplifier circuit.Famous songs which have used the fuzzbox are You've Really Got Me" by the Kinks and (I Can't Get No) Satisfaction by Keith Richards.
Chorus Pedal
This pedal attempts to imitate a group of people all playing at slightly different pitches.
Tremolo Pedal
This guitar foot pedal creates a shuddering effect on the sound.
Flanger Pedal
The development of the classic "flanging" effect is generally attributed to Ken Townsend, an engineer at EMI's Abbey Road Studio, who devised the process in the spring of 1966. Tired of the laborious process of re-recording dual vocal tracks, John Lennon asked Townsend if there was some way for the Beatles to get the sound of double-tracked vocals without actually doing the work. After mulling the problem over, Townsend devised Artificial Double Tracking or "ADT." Lennon asked Beatles producer George Martin to explain how ADT worked, and Martin answered with the nonsense explanation, "Now listen, it's very simple. We take the original image and we split it through a double-bifurcated sploshing flange with double negative feedback." From that point on, whenever Lennon wanted a Beatles song double-tracked, he would ask for "Ken's flanger". According to Lewisohn, "The Beatles' influence was so vast that the term "flanging" is still in use today, more than 20 years on. Cool eh?
Phaser Pedal
Reverb Pedal
Makes your guitar sound like it's being played in a room or a cathedral or any other kind of space.
Delay Pedal
First used by Les Paul- I'm Forever Blowing Bubbles. Paul achieved time delay by stretching audiotape between two reel-to-reel tape decks spaced several feet apart.
Graphic Equalizer Pedal
This pedal is like a glorified treble and bass control.
