Vast, intuitive tonal control
With up to 15 simultaneous effects blocks for amps, cabs, and effects, the GX-100 offers a ton of potential for crafting your custom guitar tones. And while you have complete control over all aspects of your sound and signal flow, editing on the GX-100 is fast and easy thanks to its large color touchscreen. A user-friendly interface makes it simple to execute deep tone tweaks without getting slowed down by menus. And for maximum sonic control, you can connect the GX-100 to your Mac or PC via USB for more detailed editing and preset management with the BOSS Tone Studio app.

AIRD amps with tube-like response
Packed with 23 AIRD amplifiers — the most advanced modeling amps BOSS has to offer — the GX-100 equips you with a range of tones from classic cleans and grinding crunch to metal-ready leads. Many players have lauded BOSS AIRD amp models for their tube-like response and natural-sounding breakup, delivering a responsive feel you can really dig into. To finalize your tone, you can select from a wide range of onboard speaker types, or even load your own speaker IR files for truly customized tone.
Ample routing and control options
The GX-100 is ready to integrate with practically any type of guitar or bass rig. Simply use a single cable to the input of your amp, or use the 4-cable method with your amp’s effects loop for freedom to place effects either before or after your preamp stage. Eight footswitches make it easy to navigate your settings right from the board, plus an expression pedal with toe switch offers the familiar feel of your favorite wah pedal. The GX-100 also supports MIDI input/output for more advanced control and integration with more complex stage setups.
