Häh-Audio is a Finnish boutique builder of handmade guitar effect pedals and custom audio devices. The company hand-assembles its pedals in small batches and also offers custom builds, repairs, and modifications for other gear.

Its catalog centers on dirt and tone-shaping circuits, including the Beacon, a one-knob vintage-voiced fuzz that cleans up with guitar volume, along with a mini version of the same pedal. Other releases include the Anti-Fuzz (with a Ukraine-edition variant), the Detective, the Crow's Nest, the Top Hat, and the Hugo, spanning fuzz, boost, and octave effects.

The brand fits within the broader Nordic boutique pedal scene, selling direct through its own web store and via specialist retailers and the Reverb marketplace.

Häh-Audio has 4 products cataloged on Equipboard, including Fuzz Effects Pedals, Multi Effects Pedals, and Boost Effects Pedals.
