DreamGig Foot Controllers provide remote control functionality of the DreamGig software. DreamGig Foot Controllers unlock and activates ALL software functionality. The DreamGig Software allows a Demo Only mode when used alone in order to let you have a "tour" of the functions. The addition of a DreamGig Foot Controller opens a world of easy gigging. There are two choices of DreamGig Foot Controllers. The DGC1 is recommended for "rock" style playing, or louder volume playing. The DGC2 provides quieter switching, due to more expensive switches utilized in the product, and is recommended for "acoustic" type gigging. (Note - the actual switches used are the only difference between the two controllers).
