Plan-9 Analog Effects is a São Paulo, Brazil pedal builder founded by Orlando Ferreira (known in the pedal community as "Orlando Fuzz"). The company started as a hobby project after Ferreira found vintage effects nearly impossible to source in Brazil and began hand-wiring his own units, eventually building circuits for friends before turning the operation into a full workshop.

The brand specializes in faithful recreations of classic 1960s and 1970s effects, with fuzz pedals as the core of the catalog. Notable models include the 66 Bender MkI.5 Ge, a germanium-transistor recreation of the Vox/Sola Sound Tone Bender Mk 1.5; the Fuzz Mutante Si, modeled on the Regulus VIII fuzz used by Brazilian psychedelic band Os Mutantes; the Super Wild Fuzz Si, a Univox Super-Fuzz recreation; and the Psycho Fuzz Si. The lineup also extends to octavers, boosts, phasers, and tremolos.

Pedals are built by hand with off-board wiring of jacks, switches, and pots, and Plan-9 selects and play-tests its germanium and silicon transistors individually before assembly. Units are typically housed in compact enclosures with vintage-style graphics, and the shop ships internationally from São Paulo.

Plan 9 has 8 products cataloged on Equipboard, including Fuzz Effects Pedals, Boost Effects Pedals, and Overdrive Effects Pedals.
