New Colors for Your Sound!
The GX-100 combines groundbreaking BOSS sound technologies with a sleek, modern hardware design, delivering top performance anywhere. Explore 23 AIRD amps and more than 150 effects from the flagship GT-1000, and craft outstanding sounds in just a few steps via the intuitive touch color display. Up to 15 simultaneously usable effect blocks offer unlimited sound possibilities—especially combined with deep real-time control via the built-in footswitches, expression pedal, or external control options.
Authentic Amplifiers and Speakers
The GX-100 delivers outstanding sound and a natural tube amp playing feel in every situation. This is made possible by AIRD technology and our continuously evolving Tube Logic concept. AIRD is a fundamental part of every GX-100 guitar and bass amplifier. With AIRD Output Select types, you can perfectly tailor the sound to any target—whether an amplifier, FRFR speaker, or PA system. Additionally, numerous built-in speaker cabinets are available, including the option to import your own speaker impulse responses via USB.
Outstanding Effects
With more than 150 high-quality effects from the vast BOSS library, the GX-100 lets you create virtually any desired sound. Besides numerous overdrive and distortion effects, you’ll find classic BOSS effects like Slow Gear, Octave, and more. There’s also a wide range of modulation effects, delays, and reverbs, plus plenty of effects specifically for bass. Furthermore, you can use the send/return jacks to integrate your favorite stompboxes or your amp’s effects loop into the GX-100 ecosystem.

Create Your Own Sound
The GX-100 comes factory-loaded with 100 presets so you can start playing right away. Of course, you can easily edit these presets or create your own from scratch. Let your creativity run free. With 15 independent block types—including two amplifier blocks—you can chain effects in series and parallel to produce any desired tonal variation. Plus, 200 memory slots give you plenty of room for your sounds to cover nearly every song and style.

Touch and Go
With the GX-100, sound shaping and editing live on stage is easier than ever. The high-contrast touch color display lets you intuitively control your patches and effects, adjust parameters and signal chains, and much more. Together with the screen, the four knobs and page buttons on the surface provide a smooth experience so you can always focus on the music.
Individual Control
The GX-100 offers comprehensive real-time control with eight assignable footswitches plus an expression pedal with toe switch. The switches and pedals come preconfigured for patch/bank selection and patch control. If needed, you can freely assign the switches to suit your individual needs. In Manual Mode, you can use switches and pedals like a stompbox. Even more options come from connecting external footswitches, an expression pedal, or control via MIDI. There’s also a jack for remotely switching your amp channels. Use individual memory slots or an assigned footswitch for this.

Your Studio Partner
Besides live use on stage, the GX-100 also impresses as a USB audio interface for recording with a computer. This way, you can record directly into a DAW, reamp tracks, and monitor the overall sound through the GX-100’s outputs. Practice anytime, anywhere with the headphone jack. At the same time, the built-in looper is the perfect partner for jamming, developing sounds and ideas, and creatively expanding your performance possibilities.

Full Control with BOSS Tone Studio
With BOSS Tone Studio for macOS and Windows, you can adjust every single parameter of your GX-100, save sounds, and assemble live sets for different gigs on your computer. Using the optional Bluetooth Audio MIDI Dual Adapter, you can also use the BOSS Tone Studio app on your mobile device to wirelessly tweak settings on stage while streaming background music and more from your music library.
Instrument Cable
The Stage INST cables are professional guitar/instrument cables with high-quality jack plugs and gold-plated tips. This ensures low conductor capacitance and excellent audio transmission.
