Premium BOSS tone technologies and streamlined design for endless sound creation.

The BOSS GX-100 guitar effects processor fuses advanced BOSS tone technologies with sleek, ultramodern hardware design for top-shelf performance in any setting. Explore 23 AIRD amplifiers and over 150 effects derived from the flagship GT-1000, and craft great sounds in seconds with the intuitive color touch display. Up to 15 simultaneous effects blocks deliver endless tone possibilities, coupled with deep real-time command via onboard footswitches, an expression pedal and external control support.

Authentic, tailored sound
The GX-100 features AIRD technology, backed by the BOSS-refined Tube Logic approach. The AIRD Output Select lets you customize your sound with precision for any destination, whether it’s an amp input, FRFR monitor or house PA. It also includes a wide selection of onboard speaker cabs, plus slots for importing your own speaker IRs via USB.

Effects library and preset memories
With over 150 effects, numerous overdrives and distortions, plus BOSS classics like Slow Gear, Octave and more, you can endlessly create and customize new sounds. The GX-100 also includes a diverse range of mod effects, delays and reverbs, plus send/return jacks so you can integrate your favorite stomps or effects loops. You can also dial into one of the 100 preset memories to start playing right away, edit them for your needs or build your own. Get creative with 15 dedicated block types—including two amp blocks—and chain effects in series and parallel to discover all kinds of sonic variations. With 200 user memories available, you can store enough onboard sounds for any song or style.

Player-forward design
Sound creation and on-the-gig editing are simpler than ever with the GX-100—the color touch display offers intuitive control of patch and effects selection, parameter tweaks, signal chain adjustments and much more. The GX-100 also includes deep real-time control with eight custom footswitches and an expression pedal with toe switch. They come configured for patch/bank selection and patch-specific control, but you can reassign them to meet your needs. Switching into Manual mode provides direct stompbox-like control, and you can go even further with external control via footswitches, an expression pedal or MIDI. There’s also a jack to remotely switch channels on your amp with memory selection or an assigned footswitch.
