A new dimension of expression is available with the Accel pedal, which enables control of multiple parameters simultaneously, as well as time-variant effects such as Feedbacker, S-Bend, Twist, and more. Experiment with creative combinations of parameters and bring dynamic new sounds to your performances by interacting in real time with this cool pedal.
Another notable feature in the GT-100 is the versatile A/B Channel Divider. This lets you assign different amps and effects to each channel, either for blending together or switching between them with a footswitch. Going even further, you also have the ability to switch channels by playing strength or frequency range. With each channel capable of driving its own effects and amps settings, the range of tones gets wider and wilder! You can assign smooth, mild lead tones to the mid-to-high pitches, for example, and heavy, cutting tones to the lower notes—the tonal possibilities are endless.
