The Green Rhino MKII is a high-performance overdrive pedal that builds upon the foundation of the classic TS808 Tube Screamer circuit while adding significantly more tonal flexibility. It features standard volume, tone, and drive controls, augmented by a 100Hz EQ knob and a "Curve" control. The 100Hz knob allows for a 12dB boost or cut of low-end frequencies, correcting the bass loss often associated with vintage overdrive designs. The Curve control acts as a fine-tuning tool for the corner frequencies, allowing the user to shape the character of the mid-range and high-end response. Built with a rugged aluminum chassis and high-grade components, it utilizes a quiet relay-based true hardwire bypass system.
