This pedal’s nine polyphonic pitch-shifted settings give you the power to drop your tuning from 1–7 semitones, a full octave, or a distinct octave-down setting that blends in your dry signal for enhanced clarity. No matter what setting you choose, the Drop offers spot-on and instantaneous down-pitched tracking. And despite its myriad sonic possibilities, the Drop sports a no-nonsense control scheme that consists of a single knob to choose your pitch settings and a momentary/latching footswitch.
