The electric guitar first became commercially available in the early 1930s and over the last 70 years has evolved into the instrument that we know today. The electric guitar is a versatile appliance and is used as an accompanying instrument in most styles of modern music. Invariably the guitar is crafted from wood as various types of wood have resonant qualities that are suited to sustaining and enhancing the string vibrations on a guitar.
These string vibrations are amplified by magnetic pick-ups that are normally attached to the face of the instrument and from here the pick-ups convert the plucked or strummed frequencies into electrical impulses that are fed into an amplifier in order to amplify the sound to an audible level.
The pick-ups generally fall into two categories which are single coil or double coil - also known as hum-bucking pick-ups due to their ability to cancel hum in the dual coil configuration. Each type has differing sound qualities with single coil models generally having a lighter and brighter sound whilst the hum-bucking models have a higher gain output and a deeper, mid-range tone.
