MG Music is a boutique amplifier and effects pedal manufacturer based in São Paulo, Brazil, founded in 2004 by Marcelo Giangrande. The company specializes in tube amplifiers, analog effects pedals built with rare and vintage components, and speakers, with a design philosophy rooted in the guitar tones of 1960s and 1970s rock and blues.

The pedal lineup includes models such as the Mono Vibe (a Uni-Vibe-style modulation pedal), The Drive OD, the Tony Tender, and the Alien Booster, each drawing on circuits and aesthetics inspired by classic-era effects. Giangrande's builds emphasize point-to-point construction techniques and period-correct components, which has earned the brand recognition among players seeking vintage-style tones with hand-built quality.

MG Music has 7 products cataloged on Equipboard, including Overdrive Effects Pedals, Fuzz Effects Pedals, and Delay Effects Pedals. Their gear is featured by 6 artists, with the strongest followings in Rock, Electronic, and Folk, World, & Country. Notable users include Kevin Shields, Pat Smear, and Lucio Maia.
