PHX Instrumentos is a Brazilian musical instrument manufacturer and distributor based in São Paulo, founded in 1984. The company is one of Latin America's larger percussion manufacturers and produces a broad catalog that extends into acoustic and classical guitars, electric guitars, electric basses, ukuleles, and entry-level instruments aimed at children and beginners.

Its product range is organized into several sub-lines, including Camerata and Serenna for nylon-string and acoustic guitars, Eclipse and Sunset for electrics, and Traveller for compact and travel-oriented models. PHX is also notable for being the only company in Latin America to hold Marvel and Disney licenses for musical instruments, producing themed ukuleles and starter guitars under those properties. The brand's percussion catalog covers samba and Brazilian folkloric instruments alongside more general drum and hand-percussion gear.

PHX positions itself toward the student, hobbyist, and entry-level professional segments of the Brazilian and broader Latin American market, with distribution focused regionally rather than as a globally exported boutique brand.

PHX has 2 products cataloged on Equipboard, including Solid Body Electric Guitars.
