A guitar, usually electric, featuring an offset "waist." The lower and upper sections are offset from each other. The offset waist was designed to be more comfortable when playing in a seated position. These guitars and basses were introduced in the late 50's with the Fender Jazzmaster. The guitar was embraced by the Surf music scene. This prompted Fender to release the short scale Jaguar, and many others. Some examples include the Fender Jazzmaster, Fender Jaguar, Fender Mustang, Fender Musicmaster, Fender Toronado, Jazz Bass, many Reverend guitars.
I really love to play my Offset Guitar through my '65 Fender Twin Reverb!
