What Guitar Effects Pedals Are Trying To Achieve

By Alex Dunlop

When a guitarist is looking for that 'extra' sound, they usually find it in the form of one produced by guitar effects pedals. And with such effects as distortion, delay and chorus at their disposal, the effects that can be achieved are truly music to the ears. There are vast arrays of sounds available by utilising these three effects. There is also a dedicated guitar if one should be so inclined. Let's look closer at what each of these effects do.

Distortion

The most utilised of these effects is distortion. It is the most recognisable sound as it has the most impact, both in terms of style and volume, of any guitar effects pedal. Just how much it is utilised depends upon the genre of music being performed. Heavy metal requires a crunchy sound whilst blues calls for a warmer sound. Country music uses it just enough to create a 'clean' sound.

Delay

Delay is another popular effect, related to reverb. An analogy of a delay could be the sound of the room that you're in. A large room creates a boomy sound and a small room, more distinct and brighter. In any room, you'll hear the original sound followed by the sound that reflects off the walls. The sound actually indicates the size of the room. It is essentially similar to reverb but the sounds aren't as distinct.

Chorus

The chorus splits the sound and adds a very slight delay to one of the signals. Think of when two guitarists are playing at the same time; inevitably there will always be one marginally out of synch with the other. This effect is created by the chorus effects pedal. Essentially, you think you're listening to two guitarists playing instead if one which makes for a thicker sound.

Those three guitar effects pedals form the foundation of the electric guitar sound you hear today. Which one bears the greatest impact is debatable; certain guitarist's prefer a specific effects pedal. There are some guitarist's whose preference is dictated by that of those whose music influences and inspires them. Later down the line, that sound becomes a standard. Until the next innovative creation.
