What is whammy dt?

Whammy DT is a pedal made by Digitech that combines their classic Whammy pitch-shifting technology with a drop-tuning feature. It allows guitar players to shift the pitch of their instrument up or down by various degrees, as well as drop the tuning of their strings down by up to 7 half-steps without having to physically adjust tuning pegs. This can be useful for creating unique tones and exploring new musical ideas. The Whammy DT also includes true bypass, MIDI functionality, and a momentary footswitch for more precise control.
