In 1964 the Duo-Sonic was redesigned based on the Fender Mustang that had recently been added to the student model line but without the vibrato tail-piece. Third version – Duo-Sonic II (1964–1968) The other significant change was a switch from anodized aluminum to plastic pickguards. These fretboards were originally in the slab-style but switched to the veneer style after approximately a year. The most significant change was a switch from a maple fingerboard to a rosewood one in keeping with changes to other Fender models at this time.

In 1959 the Duo-Sonic went through a face lift. The original model Duo-Sonics also sport a gold-colored, anodized pickguard that helps in screening the single-coil pickups and electronics from interference. The original model was only available in a light tan color called Desert Sand and had a maple fingerboard with 21 frets and a neck with a soft-V profile. Like the Musicmaster introduced a few months earlier, it featured basic but effective construction and a 22.5 inch scale length (standard Fender guitars feature a 25.5 inch scale) and cost $149.50 (equivalent to $1,609 in 2022). The Fender Duo-Sonic was introduced in 1956. Squier classic vibe Duo-Sonic, it copies the appearance of the first generation of Fender Duo-Sonic The bridge is fixed and the line has a shorter scale neck than standard models as a concession to younger, beginner guitarists and other players with smaller hands. The Duo-Sonic features typical Fender construction techniques with a bolt-on maple neck, attached to a solid body. The original "Duo-Sonic" features two single-coil pickups and a vertical switch on the lower horn of the body to select bridge, neck or both pickups in a humbucking style configuration (as opposed to the blade switch more common on Fender guitars). It was referred to as a "3/4 size" Fender guitar. The Fender Duo-Sonic is an electric guitar launched by Fender Musical Instruments Corporation as a student model guitar, an inexpensive model aimed at amateur musicians.
