Calico Effects is a small-batch boutique pedal builder based in Rhode Island, hand-assembling each unit one at a time. The company focuses on gain-based circuits — fuzz, distortion, overdrive, and preamp pedals — often putting their own twist on classic designs.

Their lineup includes the Antlers, an extended-range take on the Green Russian Big Muff with switchable mid voicings, gain modes, and a diode-lift option; the MFT Overdrive, a MOSFET-based drive that spans low-gain breakup to fuzzy textured overdrive; the Sunnmanor Preamp, modeled on the single channel of the Sunn Beta Bass and capable of everything from tone-shaping preamp duty to full distortion; and the Pounce Preamp, a single-knob unit that adds character rather than serving as a transparent boost.

The brand sits in the boutique fuzz and dirt niche, with circuits aimed at both guitar and bass players who want vintage-inspired voicings reworked with modern flexibility.

Calico Effects has 2 products cataloged on Equipboard, including Fuzz Effects Pedals and Overdrive Effects Pedals.
