Montreux is a Tokyo-based guitar parts and accessories company founded in 2007 by Yuichiro Shirakuma, a former Fernandes executive who previously launched the Vintage Clone parts line. The company specializes in high-accuracy reproduction and replacement parts for vintage Gibson and Fender guitars, manufactured at a network of long-standing factories in the Tokyo area.

The catalog is organized into three tiers. The Time Machine Collection aims for historical accuracy, with parts made from molds of original 1950s and 1960s Gibson and Fender components. The Retrovibe line offers convincingly aged aftermarket parts at a lower price point, and the Selected Parts range covers generic components such as jacks, pots, and bridge saddles. Typical offerings include pickguards for Les Paul, ES-335, Stratocaster, Telecaster, Jazzmaster, Jaguar, SG, and PRS-style guitars, along with knobs, tuners, bridges, tailpieces, pickup covers, and wiring hardware.

Montreux has become a common source for luthiers, restorers, and hobbyists looking to rebuild or relic vintage-style instruments. North American distribution is handled by GM Vintage Restorations, and the brand is carried by specialist parts retailers including Legacy Guitars, Guitarslinger Products, and Armstrong Music.

Montreux has 5 products cataloged on Equipboard, including Straps & Strap Locks, Guitar Bridges and Tailpieces, and Miscellaneous Guitar Parts.
