SMP Guitars is a boutique electric guitar maker founded by luthier Stuart M. Powick, based in the Surrey Hills of England. Instruments are built by hand in small numbers using selected tonewoods, and the workshop also runs 'build your own guitar' courses out of the village of Hambledon.

The lineup centers on a small set of original designs spanning traditional and modern-metal territory. The Orpheus is offered in 6, 7 and 8 string configurations with standard, multiscale and baritone scale options; the Ichor is a contemporary set-neck design; the Τρίτη (Triti) reworks the Telecaster shape into anything from a twang machine to a baritone or seven-string shred build; the Atlas takes a more classic outline with modern playability; and a headless model rounds out the range, also available in 6, 7 and 8 string versions. Custom builds and tonewood/hardware specifications are available alongside the standard models.
