MRoxy, also branded as MRoxy Handmades, is a Brazilian boutique effects pedal maker based in Belo Horizonte. The workshop builds handwired, small-batch stompboxes for guitar and bass, leaning on tube-amp voicings and classic analog circuits rather than digital modeling.

Its catalog has included tube amp emulator and booster pedals voiced after Fender, Marshall, and Mesa/Boogie amps, the Over Screamer overdrive, the Bass Man preamp modeled on a Fender Tweed Bassman, the Bass Phasor analog phaser, the Bass Singer analog chorus, and the Hot Bass preamp, alongside compressors and delays. True-bypass switching and all-analog signal paths are common across the line.

The brand is a familiar name within Brazil's handmade-pedal scene, where it sits alongside builders like Uchoa and EFX. MRoxy gear is discussed regularly on Portuguese-language forums such as Cifra Club and ContrabaixoBR, with bass players in particular citing the preamp and modulation units.

MRoxy has 1 product cataloged on Equipboard, including Chorus Effects Pedals. Their gear is featured by 1 artist, with the strongest followings in Rock. Notable users include Vitor Brauer.
