GFI System Jonassus

The Jonassus Drive is a double channel overdrive pedal. It offers a sweet, warm and dynamic low gain overdrive “Low Channel” plus a powerful and defined high-gain “High Channel”. Each channel has its own volume and gain control, a shared tone control and a push button for “Clipping” mode, to offer more sound possibilities: more dynamic, more or less compressed, warmer, etc..

The Volume, Gain and Clipping controls on the left and right side are not permanently assigned to any channel. The DIP switch setting (on the back of the pedal) gives you three different ways to assign those controls to each channel.
