SIB Electronics is a boutique guitar effects pedal company based in San Diego, California, specializing in tube-driven stompboxes. Founded by designer Rick Hamel, with Brian Aberg as co-owner, the company has been building effects pedals since the mid-1990s — predating the widespread use of the term "boutique effects." Every pedal in their Custom Shop line is hand-stuffed, hand-soldered, and individually tested by Hamel and Aberg. Hamel is also known for his collaboration with tone legend Mark Sampson (of Matchless and Bad Cat fame) on the SMF 15 Watter amplifier.

SIB Electronics is best known for the EchoDrive, a tube-driven delay pedal built around a 12AX7 vacuum tube in a Class A circuit. Widely regarded as a holy-grail delay, the EchoDrive routes the dry signal through an all-tube path while using a proprietary micro-circuit for the delay line, producing warm, tape-echo-like repeats. The Varidrive, another flagship pedal, is a pure tube overdrive that also uses a 12AX7 in a Class A design, delivering everything from subtle bluesy breakup to aggressive distortion via its drive and gain controls. Other notable pedals in the lineup include the FatDrive overdrive, Mr. Echo and Mr. Echo Plus delays, Mr. Fazedelic four-stage optical phaser, Mr. Vibromatic vibrato, Nick Nitro Fuzz octave fuzz, and Treminator tremolo.

SIB Electronics pedals have found their way onto the pedalboards of artists such as Josh Homme and Isaiah Mitchell of Earthless. The company's emphasis on real tube circuits — rather than hybrid or solid-state emulations — and hand-built construction has earned them a devoted following among guitarists seeking authentic tube warmth in a stompbox format.

SIB Electronics has 11 products cataloged on Equipboard, including Delay Effects Pedals, Overdrive Effects Pedals, and Vibrato Effects Pedals. Their gear is featured by 33 artists, with the strongest followings in Rock, Pop, and Electronic. Notable users include Isaiah Mitchell, Noel Gallagher, and Paco Huidobro.
