The Yamaha GL-1 is a guitalele, also known as a 1/4 size guitar or guitar-ukulele hybrid, combining the size of an ukulele with the wider fretboard and six single nylon strings of a classical guitar.

The guitalele combines the portability of a ukulele, due to its small size, with greater chord possibilities from six strings. In January 1997, Yamaha Corporation came out with its version, the GL-1 Guitalele.

Its dimensions are: scale length (nut to saddle) 433mm (17"); nut width 49.5mm (1?"); body length 730 mm (28¾"); body width 290 mm (11.4"); body depth 100mm (213/16").

The GL-1 guitalele has an unadorned laminated spruce top (with no rosette), laminated meranti back and sides, nato neck and rosewood fretboard. It comes tuned ADGCEA, and is played like a guitar pitched up to “A” (like a guitar with a capo on the fifth fret).
