Boss GX-100 Multi-Effects Processor — Flagship Touchscreen Engine
The Boss GX-100 is a floor-based multi-effects processor that fuses 32 AIRD amp models and over 170 BOSS effects into a touchscreen-equipped chassis. A 32-bit floating-point engine with 24-bit AD and 32-bit DA conversion at 48 kHz delivers studio-grade signal quality. Up to 15 effect blocks route in series or parallel.
AIRD Modeling and Wireless Editing
AIRD pairs each amp with a custom impulse response, delivering a finished tone without manual cab matching. Hexagonal blocks on the 480 x 272 LCD touchscreen can be dragged and stacked to sculpt signal chains. Wireless editing via the optional BT-DUAL Bluetooth adapter and BOSS Tone Studio mobile app enables full parameter control from an iPad on stage.
