2hp is a Eurorack modular synthesizer module manufacturer based in San Clemente, California, founded by Stephen Hensley. The company is named for — and specializes in — modules built at 2 horizontal pitch units wide, the smallest standard width possible in the Eurorack format. The idea for the brand emerged while Hensley was working on Qu-Bit Electronix modules, and 2hp shares a building with Qu-Bit and Electrosmith, who handle much of the manufacturing and distribution while Hensley focuses on design.

The catalog spans dozens of utility and sound-generating modules covering most of the functional blocks used in modular patching, including oscillators, filters, envelopes, sequencers, effects, and mixers, among them modules such as the Pluck, Osc, VCO, Delay, Verb, LFO, Comp, and Mix. The appeal is fitting a wide set of voices and utilities into very small cases, making 2hp popular for compact live rigs and for filling leftover space in larger systems. Modules are sold direct through the brand's web shop and through a network of international Eurorack dealers.

2hp has 55 products cataloged on Equipboard, including Modular Synthesizers. Their gear is featured by 8 artists, with the strongest followings in Electronic, Funk / Soul, and Pop. Notable users include Andrew Huang, Afterlife, and Joey Walker. Most 2hp products sit on the budget-friendly end of the spectrum.
