Musicians like Hendrix, Page and Townshend have helped transform the guitar by developing a ‘body in contact’ freedom of expression far beyond musical artistry to the point where the guitar has transcended instrument status to becoming an extension of the player.
These rock legends have struck a chord with an entire generation of young people, with their onstage antics spawning an army of air guitarists pretending to play guitar solos.
During the 1950s, the development of the electric guitar saw Fender and Gibson introduce their first solid body models. Meanwhile, a number of effects boxes were also launched to enable further manipulation of tone colours and effects. Perhaps the most popular effects pedal is the wah wah, which alters the tone of the signal to create a distinctive effect intended to mimic the human voice.
Today’s leading audio designers are bringing harmony to a new generation of guitarists by offering more functionality in an array of sonic tools at affordable prices. Harnessing the power of mixed signal ‘system on chip’ (SoC) designs, the latest guitar multi effects foot pedals are helping today’s bedroom studio guitar wannabe to become tomorrow’s professional rock star.
