All of the amps can be used with either normal guitars or those equipped with a GK pickup. Inside the unit is a wide selection of flagship effects derived from the GT-100. Most can be used with a normal guitar, allowing the processor to do double-duty as an effects processor for any guitar gig. Included are overdrives, distortions, mod effects, delay, reverb, and more, as well as intelligent harmony and other great effects. The onboard expression pedal can be used for foot volume or effects such as wah, Pedal Bend, and others. The unit features an onboard USB audio/MIDI interface, making it easy to record great amp and effect tones in any DAW.
