It takes plenty of practice and hard work to perfect a craft. Musicians who are serious about their art painstakingly spend hours to hone their skill in order to produce music that their audience would appreciate and love. Beautiful sound is not only a product of hard work and practice. It also has to do with the quality of instrument and the accessory used. A guitarist, for example, uses different accessories to come up with different guitar sound effects. One of these is overdrive which is similar to sound distortion. The effect is produced when the degree of amplification of the guitar signal is turned up beyond the point where the circuitry is able to handle it. A top overdrive effect depends upon the type of accessory used.
