Sonomatic was an Argentine guitar effects pedal brand based in Villa Devoto, Buenos Aires, known for handmade, point-to-point analog stompboxes built with high-quality components such as Wima and Panasonic capacitors, Vishay resistors, Lumberg jacks, and Alpha potentiometers. The brand built a reputation among South American players for its artisanal construction and its takes on classic circuits at a more accessible price point than imported boutique pedals.

The lineup included the Tubo 808 Deluxe, an overdrive based on the Ibanez TS808 architecture with toggles for symmetric/asymmetric clipping and adjustable low-end response; the Sonomatic Deluxe, a PT2399-based delay designed to emulate multi-head tape echo with four separate 'head' volume controls; the Cheddar delay; and the Stank Autowah envelope filter, among other overdrive, fuzz, and modulation designs.

The Sonomatic name was later retired when the operation rebranded as Electromate, and the same team eventually relocated to Miami, Florida, where they now operate as Matero Effects, carrying forward many of the same circuit designs and build practices established under the Sonomatic banner.

Sonomatic has 7 products cataloged on Equipboard, including Overdrive Effects Pedals, Delay Effects Pedals, and Wah Pedals. Their gear is featured by 4 artists, with the strongest followings in Rock, Folk, World, & Country, and Latin. Notable users include Flavio Cianciarullo, Florencia Ruiz, and Richard Coleman.
