Boss GT-1 Guitar Multi-Effects Processor

Description

The Boss GT‑1 packs professional‑grade tone into a compact, travel‑friendly design built for guitarists who want maximum versatility without the bulk of a full‑size floorboard. Powered by Boss’s flagship COSM sound engine, the GT‑1 delivers expressive amp models, studio‑quality effects, and deep editing options — all accessible through an intuitive interface that’s easy to use on stage or at home.

With 108 effects, including drives, modulations, delays, reverbs, pitch effects, and acoustic simulation, the GT‑1 covers every genre from classic rock to modern worship, metal, ambient, and beyond. The CTL1 footswitch and optional expression pedal give players real‑time control over parameters like wah, volume, delay time, rotary speed, and more.

The GT‑1 also functions as a USB audio interface, making it ideal for direct recording, re‑amping, and editing via Boss Tone Studio. Its rugged build, battery operation, and ultra‑compact footprint make it a perfect grab‑and‑go solution for rehearsals, gigs, and fly‑rig setups.
