Decibelics is a boutique guitar effects pedal company based in Barcelona, Spain, founded in 2013 by Guillem Vilademunt. Vilademunt's background as an automotive electronics engineer working on high-performance racing car electronics informs the brand's small-batch, hand-built approach, with pedals assembled in limited monthly runs that typically sell through a pre-order system.

The brand is best known for its work in the Klon Centaur lineage — the Golden Horse is a part-for-part recreation of the Centaur in a compact enclosure, while the Golden Royale packages two Centaur-style circuits into a single dual-channel overdrive. Other pedals in the lineup include the Big Klone, the Rivus overdrive, the Angry Swede (an HM-2-style heavy distortion), and The Reverend and Reverend XX, which are rooted in the BJFe/Guyatone Expandora EXP-2000 circuit.

Decibelics operates as a largely one-person workshop rather than a mass-production manufacturer, and its pedals are distributed directly as well as through retailers such as Reverb and Guitar Center. The brand has drawn attention in the boutique pedal community and coverage from outlets including Guitar Pedal X and Delicious Audio.

Decibelics has 9 products cataloged on Equipboard, including Overdrive Effects Pedals, Distortion Effects Pedals, and Fuzz Effects Pedals. Their gear is featured by 5 artists, with the strongest followings in Rock, Metal, and Pop. Notable users include James Murphy (Guitarist), Ola Englund, and Chris Buck.
