HeadRush is a guitar technology brand under the inMusic Brands umbrella, headquartered in Cumberland, Rhode Island. Launched in 2017, HeadRush entered the amp modeling and multi-effects market with the HeadRush Pedalboard, a floor processor distinguished by its large touchscreen interface and quad-core DSP engine. The brand leverages the legacy of Akai Professional (also an inMusic brand) and offers over 600 amp, cabinet, and microphone models across its product line, powered by proprietary modeling technology.

The HeadRush lineup spans multiple form factors: the flagship Pedalboard and Prime (which adds amp cloning via "SuperClone" technology, vocal processing with built-in Antares AutoTune, and cloud connectivity), the compact Gigboard and MX5 for pedalboard-friendly rigs, the Core and VX5 vocal processors, and the Flex Prime. The brand also produces FRFR (Full Range Flat Response) powered speakers, including the portable Bluetooth-equipped FRFR GO, designed specifically for use with modelers. On the software side, the ReValver Suite provides amp modeling and cloning capabilities for studio use.

HeadRush endorsers include Charlie Benante (Anthrax), Rex Brown (Pantera, Down), Tracii Guns (L.A. Guns), Brian Robertson (Thin Lizzy, Motörhead), Nili Brosh (Cirque du Soleil), Dan Vadim Von (Morbid Angel), and Zakk Sandler (Falling in Reverse), among many others. The brand competes in the crowded digital modeling space alongside Line 6, Kemper, and Neural DSP, carving out a niche with its touchscreen-centric workflow and aggressive pricing.

Headrush has 15 products cataloged on Equipboard, including Multi Effects Pedals, Guitar Amplifier Cabinets, and Speakers & Accessories. Their gear is featured by 31 artists, with the strongest followings in Rock, Metal, and Pop. Notable users include RJ Kaye Kaneao, Lee Malia, and Jane Remover.
