Relish Guitars is a Swiss guitar maker based in Lucerne, founded by childhood friends Silvan Küng and Pirmin Giger. Frustrated by what they saw as decades of stagnation in electric guitar design, the pair set out to rethink the instrument from the ground up. Their guitars are handcrafted in their Lucerne workshop using a distinctive construction method that sandwiches a milled aluminum frame between wood veneers, resulting in extended sustain and a unique tonal character.

The brand's signature innovation is a patented tool-free pickup swapping system that lets players change pickups in seconds without soldering or special tools. This system supports pickups from multiple manufacturers, including Seymour Duncan, Bare Knuckle, and Cream T, giving players access to a wide range of tones from a single instrument. Many models also offer an integrated Ghost Piezo pickup for acoustic-like sounds. Other notable design choices include woven bamboo fretboards as an alternative to traditional rosewood.

Relish's core lineup includes the Jane, a semi-hollow model built around the aluminum core with a maple neck and walnut top, and the Mary, a more affordable variant available with either aluminum or wood center sections. The Trinity series, manufactured in Indonesia, serves as an entry-level option that still incorporates the pickup swapping system. The company also collaborates with British pickup maker Cream T, whose guitars are built around Relish's patented pickup swapping technology. Artists who play Relish guitars include jazz guitarist Lionel Loueke, Motörhead's Phil Campbell, and Joel Van Dijk of Aloe Blacc's band.

Relish has 7 products cataloged on Equipboard, including Solid Body Electric Guitars, Extended Range Guitars, and Semi-Hollowbody Electric Guitars. Their gear is featured by 6 artists, with the strongest followings in Rock, Blues, and Metal. Notable users include Herman Li, Phil Campbell, and Toshihiko Takamizawa.
