GFI Systems Jonassus Drive

The GFI System Jonassus Overdrive is a dual-channel OD—a warm, articulate low-gain overdrive, the Low Channel, and a medium-high gain overdrive, the High Channel. The channels share a tone knob and each has its own independent controls for volume and gain. It also features independent clipping mode options: diode/asymmetric for more compression, diode/symmetric for more balance and less compression, and LED/symmetric for openness and warmth.
