Iannucci Audio is a boutique guitar effects pedal builder based in Argentina, focused on vintage-inspired, hand-wired fuzz, distortion, and overdrive circuits. The shop builds units one at a time, leaning on new-old-stock components and 1960s/70s circuit topologies rather than modern reissues — an approach intended to preserve the noise floor, microphonics, and tonal quirks of period-correct hardware.

The catalog is organized into a Vintage Series, a Signature Series, and a Custom Shop, alongside DIY kits and footswitch utilities. Notable models include the Klonucci (a Klon-style overdrive), the King Overdrive, the Hammer, the Lemon Tone MkII, the Haze Silicon and Haze Germanium fuzzes, the Mendez II distortion, the Ryu, the Karn, the Bleu, the Retrostudio 424, the Reverb 05, and various numbered Fuzz and Distortion circuits. Each unit is component-matched and tested by hand rather than assembled on a production line.

The brand sells direct from its own site and is also distributed through Reverb and Guitar Center, and it offers DIY kits such as La Llama Feliz and Tommy for builders who want to assemble pedals themselves.

Iannucci has 2 products cataloged on Equipboard, including Fuzz Effects Pedals and Overdrive Effects Pedals. Their gear is featured by 1 artist, with the strongest followings in Rock, Pop, and Funk / Soul. Notable users include Ariel Pozzo.
