This pedal extracts only the down-tuning function from DigiTech's Whammy DT. It can lower the pitch by up to 7 semitones or one octave. When lowering by one octave, you can choose whether to include the original pitch or not. The toggle switch on the upper right allows you to select momentary operation. It was used for about 1-2 years in live performances and studio sessions. I stopped using it after that and it has been in storage, so I'm putting it up for sale. It works perfectly. The pedal itself is the only item included.
