Spooky Circuits is a small, hand-built effects pedal and instrument operation run by Kevin Pontrelli. The brand focuses on boutique, often one-off builds that reinterpret classic circuits through an experimental lens, and offers a custom shop for commissioned work alongside its standard catalog.

The lineup includes the Spooky Boost, a clean boost that combines Echoplex EP-3 preamp and Tillman FET preamp circuits with a toggle between the two voicings; the Harm + Balance, a fuzz based on the Interfax Harmonic Percolator that pairs a germanium PNP transistor with a silicon NPN transistor and adds switchable clipping diodes for asymmetrical combinations; and the Wee-Bird Reeverb, a lo-fi reverb known for drifting from subtle ambience into more unstable, saturated textures.

The brand is known within the boutique pedal community for bass-friendly voicings, hands-on tweakability, and a willingness to build unusual or one-off designs for individual players. Spooky Circuits has appeared at events such as the Synth and Pedal Expo and is carried by boutique retailers including Perfect Circuit.

Spooky Circuits has 1 product cataloged on Equipboard, including Reverb Effects Pedals.
