Mask Audio Electronics is a small-batch guitar effects pedal company founded by Alec Breslow, with pedals built by hand in an attic outside of Pittsburgh, Pennsylvania. The brand grew out of Breslow's DIY pedal-building projects into a line of production effects, with a focus on fuzz and noise circuits. Aesthetic and graphic design is handled by Jordan Clayton of Pine Box Customs, giving the pedals a distinctive visual identity.

The lineup leans heavily on fuzz, with offerings such as the Black Math (a wide-bandwidth fuzz aimed at baritone, bass, and other low-register instruments), the Part Garden dual fuzz, the Civil Math, Clubber Lang, Neckbrace, Trust Yourself, Maybe, Alone, and Hot Water. Alongside finished pedals, the company sells DIY circuit boards for builders who want to assemble their own effects, reflecting the brand's roots in hobbyist pedal construction.

Mask Audio Electronics distributes through its own web store as well as a network of independent dealers, including custom shop runs such as a Guitar Shop PGH exclusive version of the Trust Yourself.

Mask Audio Electronics has 13 products cataloged on Equipboard, including Fuzz Effects Pedals, Distortion Effects Pedals, and Phaser Effects Pedals. Their gear is featured by 3 artists, with the strongest followings in Rock and Metal. Notable users include Frank Iero, Dave Sagan, and Dennis Mikula.
