A guitar effects (FX) pedal, also referred to as a stomp box, manipulates the electric signal produced by guitars to produce a variety of different sounds for the application of music. Musicians use guitar effects to produce sonically different and interesting sounds for the sake of performance, creation, and art. Although the different types of effects are numerous, the basic effects fall into either distortion, modulation, or delay. The use of guitar pedals allows the musician to accurately perform desired pieces of music or compose new songs.
The current guitar pedal market includes many effects by many manufacturers, however many of the pedals cost over $100 and include a minimal selection of effects. Although there are many ways to manipulate audio signals, Digital Signal Processing offers an inexpensive way to produce multiple effects using minimal amounts of hardware. An inexpensive, good sounding pedal that includes multiple effects would allow more musicians to use effects in their music.
