The history of the electric guitar is the story of how an ordinary stringed instrument gained an almost infinite palette of tones and became a powerful controller of sound.

It all began with a need for sheer volume. The first electric guitars were built simply so that a musician could cut through the loud horn section of a swing band. It soon became clear, however, that doing without a traditional sound box opened up entirely new possibilities for experimenting with tone.

The breakthrough came when guitarists began deliberately overdriving their amplifiers. The clean tone gave way to a dirty, aggressive sound that completely changed the face of music. Right after that came the wave of analogue effects. Small floor pedals appeared that could shape the sound to resemble a human voice, a spacious wave or cosmic modulations. The guitar was no longer just an accompanying instrument – it had become a generator of extraordinary sounds.

The natural next step was the desire to connect the guitar with the world of synthesizers. The first attempts were purely technical: special, futuristic instruments were built that resembled a guitar only in shape, but inside were complex electronic controllers. They required the musician to learn to play almost from scratch and to give up the natural ring of the strings.

Not long afterwards an intermediate technology appeared – systems with additional, dedicated pickups mounted on traditional guitars. They picked up the signal from each string separately and sent it to external sound modules. At last a guitarist could play his own favourite instrument while triggering the sounds of a piano, a string section or analogue synthesizers, although this still meant a tangle of special cables and extra equipment.

The final revolution has come in our own time, thanks to digital signal processing. Today the technical barrier has disappeared altogether. A musician no longer has to fit any additional pickups to the guitar or use complicated controllers. It is enough to plug an ordinary, traditional jack cable into a modern effects unit or a computer to get full polyphonic synthesis at once. The guitar has become a universal interface of expression – keeping its natural articulation and playing dynamics, it lets the artist sound like anything they can dream of.
