Sabbadius Electronics is a boutique guitar effects builder founded by Nicolás Sabbadin in Córdoba, Argentina. Sabbadin began constructing pedals for sale in 2002 and registered the Sabbadius trademark — a portmanteau of his surname and "Stradivarius" — after completing advanced electronics studies. The shop's design sensibility is rooted in Sabbadin's admiration for Jimi Hendrix and Stevie Ray Vaughan, with much of the catalog aimed at recreating and refining late-1960s tones.

The brand is best known for its Funky-Vibe line, a family of hand-wired univibe-style pedals that includes the Funky-Vibe RS (Real Size), the smaller 68 and 69 Tiny-Vibe, the Chewy-Vibe, the Fillmore East Tiny-Vibe, the Maui Funky-Vibe, and the Woodstock Edition. Alongside the vibes, Sabbadius builds a range of fuzz and distortion pedals such as the JIMI Fuzz v2, Electric Church BC183 Silicon Fuzz, Rainbow Fuzz BC108c, Love Drops Fuzz, Mr. White Special, Black Gold Distortion, and the octave-fuzz Rocktavia (inspired by Hendrix tribute guitarist Randy Hansen). The company also produces TRS and DIN expression foot controllers for use with its vibe pedals.

Sabbadius operates as a small custom shop, distributing through specialty boutique dealers internationally rather than mass retail. Its reputation within the boutique pedal community centers on hand-wired construction and faithful vintage-voiced circuits, particularly in the univibe space where the Funky-Vibe family is frequently cited alongside other high-end recreations of the original Shin-ei design.

Sabbadius has 8 products cataloged on Equipboard, including Univibe & Rotary Effects Pedals, Overdrive Effects Pedals, and Compressor Effects Pedals. Their gear is featured by 9 artists, with the strongest followings in Rock, Blues, and Folk, World, & Country. Notable users include John Mayer, Lula Bertoldi, and Jimmy Rip.
