Barullo is a small Spanish boutique builder based in Galicia that designs guitar effects pedals and Eurorack modules with a focus on extreme, noisy, and experimental tones. The operation grew out of the DIY and noise scene, and its catalog favors distortion, fuzz, and feedback-driven circuits rather than cleaner utility effects.

The pedal lineup includes the Alude, a Russian Muff-inspired fuzz with multiple clipping options (silicon, germanium, and an unclipped voice); the Cat, a Rat-style distortion; and the Guillotina, a choppy tremolo. On the modular side, the Ciobra is a Eurorack distortion and feedback module built around a high-gain circuit with a blend control between dry and distorted signals, Low/High shelving EQ, an internal feedback loop, a VCA, and extensive CV control over its parameters.

The brand trades under the name Barullo FX and is known within the boutique pedal and Eurorack communities for compact, aggressive designs aimed at sludge, noise, drone, and experimental players.

Barullo has 1 product cataloged on Equipboard, including Fuzz Effects Pedals.
