Fire Custom Shop is a Brazilian manufacturer of analog effects pedals, power supplies, pedalboards, and accessories for electric guitar and bass, based in São Paulo. The company designs and builds its products in-house, with a catalog spanning overdrive, fuzz, delay, and wah circuits alongside utility gear like isolated power supplies and speaker simulators.

The brand is best known for its Carpe Diem overdrive, a two-channel pedal voiced after vintage Marshall amp tones with switchable Classic (JTM45-style) and Hot Rod (JCM800-style) modes, which earned a That Pedal Show special edition run. Other notable releases include the Sweet Chilli overdrive, the Kronos delay with a Vintage/Modern voicing switch, and the hand-wired Bobber Wah, which has been used by Richie Kotzen.

Distribution reaches beyond Brazil through retailers including Guitar Center in the United States and a presence on Reverb, giving the company international visibility while keeping manufacturing in São Paulo.

Fire Custom Shop has 11 products cataloged on Equipboard, including Overdrive Effects Pedals, Phaser Effects Pedals, and Boost Effects Pedals. Their gear is featured by 9 artists, with the strongest followings in Rock, Blues, and Funk / Soul. Notable users include Juninho Afram, Mateus Asato, and Richie Kotzen.
