Mega Multi-FX with Next-Generation Amp Modeling

The long-awaited follow up to the GT-10 has arrived. Meet the new BOSS effects flagship, the GT-100, boasting next-generation amp modeling that recreates vintage amps as well as providing new COSM tones that soar into the future. The user interface has been improved with a unique dual-LCD system, and EZ TONE has been enhanced with newly designed AMP CUSTOMIZE and OD/DS CUSTOMIZE features. The GT-100 is a powerhouse processor that spans from classic to futuristic in a friendly, rugged, road-worthy unit.

  • - Advanced COSM amps that model vintage amp tones and delivers never-before-heard tones
  • - Dual-LCD for simple and intuitive operation with direct access to every parameter
  • - Improved EZ Tone TONE feature with graphical TONE GRID for constructing new patches; AMP CUSTOMIZE and OD/DS CUSTOMIZE lets you easily create original amps and overdrive/distortion by customizing their behavior
  • - Newly developed ACCEL pedal for simultaneous control of multiple parameters

Realize the impossible with Advanced Amp modeling

With its next-generation COSM processor, the GT-100 ushers in a new era of expression and sonic capability. Recreating the meticulous details of vintage amps and how they behave, the GT-100’s Advanced Amps excel in not only cloning classic amps, they also provide a new world of unimagined tone by delivering ultra-natural sounds considered to be physically impossible with existing amps. There are eight types of built-in amp models that faithfully translate the guitarist’s unique characteristics and picking nuances — including Stack Crunch (combining vintage combo amp-response with the powerful feel of stack amps) and Full Range (providing a broad frequency range and extremely flat response). Also onboard is the new T-Comp — a parameter for operating the unique compression of tube amps. This is the true value of COSM technology, which is capable of expressing the most subtle and expressive nuances.

Vintage Amp reproduces every detail of masterpiece amps

The GT-100`s newly enhanced Vintage Amp mode reproduces every detail of the tonal quality and playing feel of vintage amps. You have 17 different types at your fingertips that cover a diverse range of masterpiece amps. In addition, with T-Comp you can create sounds that emphasize the compression you get from tube amps. Also, you can change your speaker and cab configuration as well as mic settings to customize your amp any way you like — another advantage available only with COSM.

Completely new user interface with dual displays. Quickly and directly control the GT-100’s range of advanced features.

With its dual LCD display, the GT-100 puts you in direct contact with the editing functions you need without having to switch screens. When editing effects, for example, you can control the parameters on the right-side screen while viewing the audio routings on the left screen. The large LCD offers excellent visibility and helps you make accurate settings even on a dark stage.

The highly popular EZ Tone function has now become even more powerful!

The EZ Tone function makes complex editing fast and easy. Patch Create mode lets you design sounds based on musical genres and song concept. Amp Customize and OD/DS Customize let you tweak the characteristics of your amp and overdrive/distortion to your preference. You can easily operate the sophisticated and complex parameters on a graphical screen using intuitive and simple knob operations.

Get Creative with the ACCEL Pedal. Step into a New Dimension of Expression!

Step on the new Accel pedal and modulate your sound dynamically in real time. The pedal enables real-time control of multiple parameters simultaneously, as well as time-variant effects such as Feedbacker, S-Bend, Twist, etc.; Laser Beam and Warp add extreme effects that resemble synth tones. Experiment with creative combinations of parameters, interacting in real time with the pedal.

New A/B Channel Divide Function

Another notable new feature onboard the GT-100 is the versatile A/B Channel Divide. Assign different amps and effects to each channel, and divide the signal not only by dynamics, but by frequency as well, with each channel capable of driving its own effects and amps settings. The range of tonal possibilities gets wider, and wilder! Assign smooth, mild lead tones to the mid-to-high pitches, for example, and heavy, cutting tones to the lower notes.

Overdub and loop to create innovative solos and phrases

The GT-100 is equipped with the popular Phrase Loop function from the BOSS RC series, offering up to 38 seconds of recording in mono. You can switch the tone on GT-100, and overdub your performances to create expressive, innovative solos and phrases.

Record the high-quality GT sound directly to your DAW

You can connect the GT-100 to your PC/Mac via its USB audio/MIDI port, which lets you incorporate the
GT-100’s powerful amp functions into your music production directly with no loss of quality. A custom librarian program is included for backing up and managing your GT-100 effects via computer.
