Digitech BASS WHAMMY-V-01

The Bass Whammy pitch shift pedal gives you nine different expressive modes to shift and slide your notes at different musical intervals. Instantly shift up two octaves to play a lead line, or drop your bass another octave for ultra-low bass lines. Even at extreme settings, the Bass Whammy sounds surprisingly fluid. One thing Sweetwater bassists especially like is that you've got two options: you can shift your entire bass tone, or layer the pitch-shifted tone on top for harmony effects that leaves your fundamental tone intact.
