Axess Electronics is a Canadian guitar audio brand founded in 1998, specializing in signal-routing and utility tools for professional guitar rigs. The company built its reputation around buffers, amp switchers, audio routers, patch-boxes, ground-loop isolators, and MIDI switching systems — the kind of behind-the-scenes hardware used to manage complex pedalboards and multi-amp setups. Its switching and MIDI systems have been used in the rigs of a number of high-profile touring guitarists, including Van Halen, Alex Lifeson, Peter Frampton, Richie Sambora, and John Petrucci.

In 2012, founder Mario Marino was hired by Mesa/Boogie as a product lead designer, where he worked on buffers, switchers, routers, and amplifier development. Axess Electronics was reactivated in 2022–2023 under a new product line branded AXSGTR, expanding beyond utility hardware into effect pedals. Its first pedal release, the OBViouS Boost/Overdrive, was designed as a front-end boost and drive tailored for Marshall-style tube amps, with controls for Level, Gain, and Treble alongside voicing toggles and true-bypass switching.

The brand's catalog also includes products like the GRX4 guitar router/switcher and the BS2 buffer, reflecting its continued focus on pedalboard infrastructure alongside the newer AXSGTR-branded effects.

Axess Electronics has 7 products cataloged on Equipboard, including Switch Effects Pedals, MIDI Foot Controllers, and Boost Effects Pedals. Their gear is featured by 16 artists, with the strongest followings in Rock, Metal, and Pop. Notable users include Alex Lifeson, John Petrucci, and Pete Loeffler.
