The Fender Mustang was introduced in August 1964 before the sale of Fender Electric Instruments to CBS. The idea was to create a mid-line model between the student grade DuoSonic, and the professional Telecaster. The Mustang was a very popular model, and was made until 1981. Originally designed with a 22.5 inch scale guitar, the Mustang is almost always found with a 24.25 inch scale. Early models had a slab alder body, but it was given the patented Fender contour body in early 1969.
