the GNX3's power to unleash a guitarist's creative potential is fully realized in song writing. By utilizing the built-in drum machine and bass amp modeler, a guitarist can first lay down rhythm tracks on the built-in 8-track recorder. Then selecting from the GNX3's unlimited library of amp models, DigiTech's exclusive and powerful CIT™ (Cabinet Imaging Technology) feature, and a complete set of on-board effects, the guitarist can then lay down the guitar tracks. When that's finished, vocals can then be recorded on the remaining tracks using the balanced XLR mic input on the rear of the GNX3™. Even keyboards and DJ scratching can be added through the rear-panel instrument input. There's no limit! Plus, recording time can be greatly increased utilizing the SmartMedia™ card slot on the rear panel.
