Black Bug is a Brazilian manufacturer of guitar effects pedals aimed primarily at the domestic entry-level market. The company produces a line of compact, MXR-style cast-aluminum stompboxes covering common effect categories, including the Yellow Distortion (TYD-2), TRT-2 Red Tube distortion, Black Metal Distortion, Orange Tscreamer Tots overdrive/distortion, Phaser 900, Blue Space phaser/flanger combo, Silver TSC chorus, White TWD delay, TBC compressor/sustainer, and Blue TBB booster.

The brand's pedals are distributed through Brazilian retailers and online marketplaces such as Miyata Music, Magazine Luiza, and Mercado Livre, and they have been on the market since at least the early 2000s. Black Bug has built its reputation around affordability and a wide catalog spanning dirt, modulation, time-based, and dynamics effects rather than boutique-tier components, making the line a common first-pedal choice among hobbyist players in Brazil.

Black Bug has 4 products cataloged on Equipboard, including Phaser Effects Pedals, Chorus Effects Pedals, and Compressor Effects Pedals.
