The Telecaster is a versatile guitar, usable for most styles of music and has been used in many genres, including country, reggae, rock, pop, folk, soul, blues, jazz, punk, metal, alternative, indie rock, and R&B. The base model has always been available, and other than a change to the pickup selector switch configuration, a thinning of the neck, and a few variations on the bridge design, it has remained recognizable and mostly unchanged from the 1950s. Several variant models have been produced over the years including those with different pickup configurations and electronics, semi-hollow body designs, and even a twelve string model.
