BOSS GX-1 Guitar Effects Processor

The BOSS GX-1 is an ultra-portable amp and effects processor for guitar that delivers premium BOSS sound and features in a compact, battery-powered form factor ideal for practice, recording, and on-the-go performance. Featuring authentic tube amplifier tone and touch response through BOSS's AIRD (Augmented Impulse Response Dynamics) technology, the GX-1 provides 23 amplifier types and over 140 effect types with eight simultaneous effect blocks—putting a complete professional-grade guitar rig in a package that fits in a guitar bag.

The GX-1's color graphic display and intuitive effect category buttons make building sounds fast and approachable, while the innovative Gear Suite allows rapid configuration of amp and effect settings with a single knob turn. Ninety-nine ready-to-play preset memories and 99 user memories provide ample storage, and the built-in 38-second phrase looper (19 seconds stereo) adds live performance and practice capabilities. Internal tuner detection accuracy of ±0.1 cent ensures precise pitch monitoring at all times.

Bluetooth connectivity enables wireless jamming with mobile devices, streaming backing tracks, and app-based editing via BOSS Tone Studio. USB-C supports computer recording with 24-bit AD and 32-bit DA conversion at 48 kHz. The GX-1 operates on four AA batteries (approximately 5 hours), AC adaptor, or USB bus power for maximum flexibility. Optional wireless footswitch support expands live performance control beyond the onboard controls.
