GNI is a Brazilian manufacturer of guitar and bass effects pedals, known for all-analog designs and a range that covers overdrive, distortion, fuzz, and modulation effects. The company emphasizes extended field-testing of each new circuit before production and offers both a compact Pocket series of affordable entry-level pedals and a full-sized line of multi-function stompboxes.

Notable models in the catalog include the Dual Drive, the Multi Fuzz & Vintage Distortion, the X-Treme Distortion, the Shred Pro, the OctaFuzz, and the Analog Stereo Dual Chorus. Many of the pedals carry a two-in-one design philosophy, combining related effect voicings in a single enclosure.

GNI has developed signature pedals in collaboration with Brazilian bassist Felipe Andreoli of Angra and guitarist Kiko Loureiro of Megadeth, and the company has also worked with American guitarist Andy Timmons as an international endorser.

GNI has 17 products cataloged on Equipboard, including Chorus Effects Pedals, Fuzz Effects Pedals, and Multi Effects Pedals. Their gear is featured by 8 artists, with the strongest followings in Rock, Metal, and Blues. Notable users include Roger Franco, Andy Timmons, and Andy Wood.
