MacBeth Studio Systems is a boutique analog synthesizer maker based in Edinburgh, Scotland, run as a one-person operation by designer Ken MacBeth. MacBeth got his start as an electrical engineer building DIY analog synths in his spare time after being inspired by 1970s prog-rock keyboard players, eventually formalizing his work into a commercial line of hand-built instruments. The brand is known for an uncompromising approach to traditional analog circuit design, often sourcing vintage-era components in pursuit of a classic sound.

The company's catalog centers on monophonic analog synthesizers and modules in both Eurorack and Dotcom formats. Notable instruments include the M3X, a 4U rackmount monosynth; the M5, a semi-modular voice patterned after the ARP 2600 with expanded routing; the Micromac, a compact three-VCO monophonic synth; and the Elements, an all-in-one analog synthesizer with a touch-strip keyboard. MacBeth also released the larger Elements One modular system and the Exacta synthesizer.

MacBeth instruments occupy the high end of the boutique synth market, with prices and limited availability reflecting their hand-assembled construction. The brand has a devoted following in the modular and analog synthesizer community, and reviews in publications such as Sound on Sound have highlighted the build quality and sonic character of the M3X and Elements.

MacBeth has 8 products cataloged on Equipboard, including Modular Synthesizers, Straps & Strap Locks, and Synthesizers. Their gear is featured by 14 artists, with the strongest followings in Electronic, Rock, and Orchestra. Notable users include Deadmau5, Thomas DeLonge, and Mike Dirnt.
