Effettidiclara is an Italian builder of handcrafted guitar and bass effects pedals based in Rome. The company designs, assembles, and finishes each unit by hand, and operates as a small workshop that also offers custom modifications (such as the "Clara mod" for the Dunlop Cry Baby wah), pedalboard wiring services, and amplifier work.

The lineup includes pedals named after women — Agata, Camilla, Dana, Greta, Lena, Orla, Petra, Rebecca, and Tessa — covering boost, overdrive, fuzz, and reverb territory. The Agata is a high-headroom dual booster/overdrive marketed as suitable for both guitar and bass, the Petra is a fuzz with a gating "S-Ness" control aimed at synth-like and noise textures, and the Rebecca is an analog spring reverb. Effettidiclara also documents the rigs of touring musicians on its website, with gear breakdowns covering players from bands such as Verdena, Mudhoney, Godspeed You! Black Emperor, St. Vincent, Bardo Pond, and Il Teatro degli Orrori.

Effettidiclara has 5 products cataloged on Equipboard, including Fuzz Effects Pedals, Switch Effects Pedals, and Overdrive Effects Pedals.
