Kappa Electronics is a Brazilian manufacturer of handmade guitar effects pedals. The brand is known for building extended-range takes on classic circuits, offering its own interpretations of designs reminiscent of the Z.Vex Fat Fuzz Factory, the Big Muff, Marshall-style distortion, Orange Rockerverb and Mesa/Boogie Dual Rectifier tones, typically with added controls and tone-shaping options beyond the originals.

Its lineup spans fuzz, distortion, overdrive, modulation and reverb. Notable models include the Fuzzion, a fuzz pedal built around Soviet germanium transistors with a Big Muff-style tone stack, along with the Antagonist overdrive/distortion with switchable clipping, the Flow modulation pedal, the Cosmos reverb, and the Apache, Joker, Kremlin, Krusher and Pumpkin pedals. The company sells primarily through its own site and Brazilian marketplaces such as Mercado Livre, with competitive pricing that has helped give it visibility within the South American pedal scene.

Kappa Electronics has 4 products cataloged on Equipboard, including Boost Effects Pedals, Distortion Effects Pedals, and Fuzz Effects Pedals.
