The DigiTech Whammy DT is a dual-function pitch-shifting pedal that combines the classic pitch-bending of the DigiTech Whammy with a dedicated polyphonic "Drop Tune" section. It allows guitarists to shift their entire tuning up or down in semitone increments (up to 7 half-steps) or an entire octave without physically retuning their instrument.Key FeaturesDual Engine Design: The pedal features two independent sections that can be used separately or simultaneously.Left Side (Whammy): Traditional pitch-shifting effects (up/down 2 octaves), harmonies, and detune (chorus-like) modes controlled by the expression pedal.Right Side (Drop Tune): Step up or down in 7 half-steps or a full octave. Includes a Momentary footswitch for instant, temporary pitch shifts, useful for hammer-on and pull-off style effects.Polyphonic Tracking: Uses advanced algorithms to track full chords accurately, which is a major upgrade over early monophonic models.True Bypass & MIDI: Includes a True Bypass mode for signal integrity and a MIDI input for remote control of patch changes and expression settings.Additional Connectivity: Features an input for an optional DigiTech FS3X footswitch to navigate presets hands-free. New in box. Opened for inspection
