There is a type of overdrive pedal that delivers variations on its voice via a switchable selection of clipping options – and this certainly offers versatility. But the Kernom Ridge goes further by delivering its clipping options via a rotary Mood knob, the actual overdrive voice being determined by the knob’s position. 

The new technology behind this, ‘analog morphing core’, is said to control the non-linear elements of the clipping stage, changing their threshold in real-time. Kernom says the Mood knob is roughly divided into five segments, running from a clean and open sound through transparent overdrive, a more coloured overdrive and high gain, to ‘almost fuzz’.
