Between 1932 and 1949, several craftsmen and companies had experimented with solid-body electric guitars, with little success. Leo Fender created and marketed the Telecaster in February 1951. The Telecaster had a bright rich cutting tone. From its' inception, the Tele began its steady ascent toward stage and studio indispensability.

In 1954, Glen moved to Albuquerque to join his uncle’s band, known as Dick Bills and the Sandia Mountain Boys. Early pictures reflect that Glen came to town playing his Telecaster.
One of the earliest pictures of Glen playing his Telecaster was at, what is said to be, a Safeway store, in 1954 (If you look closely, Glen's Tele had a Bigsby on it.):
