The long-awaited follow up to the BOSS GT-10 has arrived.

The BOSS GT-100 multi-effects pedal is a powerhouse designed for guitarists seeking an all-in-one solution for crafting and controlling tone. Equipped with BOSS's latest COSM technology, the GT-100 provides authentic emulations of classic tube amps along with futuristic tones never before possible. Its dual-LCD interface and eight knobs provide intuitive control over deep editing parameters without complicated menus.

Next-Generation COSM Technology for Vintage and Modern Tones

The GT-100's advanced COSM processor enables emulations of meticulously modeled vintage amps as well as otherworldly tones. The Amp Customize function allows you to manipulate classic amp models into entirely new sounds. Sculpt your tone from warm, tube-like overdrive to searing distortion and anything in between. With the GT-100, your sonic options are nearly limitless.

Intuitive Interface for Fast Tone Crafting

Tone editing is intuitive and inspiring thanks to the GT-100's dual-LCD display and hands-on knob controls. There are no complicated menus to navigate. Easily view and adjust amp, effects and system parameters on the fly. The Tone Grid allows you to create patches, amp models and overdrive/distortion effects from scratch or customize existing presets to your needs. Editing tones has never been more direct or gratifying.

Versatile A/B Channel Divide

The GT-100's A/B Channel Divide feature provides even more tonal versatility. Assign different amps, effects, dynamics and frequency ranges to each channel for a multitude of possibilities. For instance, select a clean tone for the A channel and a distorted lead tone for the B channel. Or, assign lower frequencies to one channel and higher frequencies to the other. The creative options are endless.

Expression Pedal Control Over Multiple Parameters

Connect an expression pedal to the GT-100 for real-time control over multiple effects parameters at once. Manipulate time-based and modulation effects like Feedbacker, S-Bend and Twist for experimental sounds. The Accel Pedal mode allows you to control the speed and intensity of effects in an intuitive manner. Push the boundaries of tone shaping with an expression pedal and the GT-100.
