Used Boss GX-100 multi-fx

If you want Helix-level flexibility, studio-grade processing, and seamless gigging controls without the headache of endless menu-diving, the BOSS GX-100 is a modern game-changer.

Positioned right between the compact ME-90 and the flagship GT-1000, the GX-100 combines BOSS’s top-tier AIRD (Augmented Impulse Response Dynamics) technology with a slick, color touchscreen interface. It gives you absolute freedom to build complex, custom signal chains in seconds, making it one of the most powerful and intuitive multi-effects units on the market today.

AIRD Tech & Flexible Signal Chains

At the core of the GX-100 are 23 AIRD amplifier models and over 150 BOSS effects pulled directly from the flagship GT-1000.

• AIRD Amp Modeling: Instead of static amp snapshots, BOSS’s AIRD technology models the real-time interaction between every component inside a tube amp—from the input transformer to the power tubes and speaker cabinet. The result is authentic tube feel, dynamic pick response, and natural breakup under your fingers.
• Up to 15 Simultaneous Blocks: You aren't locked into a rigid signal flow. The GX-100 lets you drag, drop, and place up to 15 effects and amp blocks in any order you want—including parallel routing paths for splitting your signal between clean and heavy amps, or running stereo delays and reverbs.
• IR Speaker Support: Load your own custom speaker Impulse Responses (IRs) or choose from a wide library of built-in BOSS speaker cabs.
