A compact effects pedal with adjustable pitch. It was very useful because it allowed me to easily raise or lower the pitch. It's similar to the Digitech Drop, but this one can also raise the pitch. I didn't use any functions other than the pitch shifter, so I'll omit them. I'm selling it because I bought a Boss XS-1. The unit only. I am also selling on another site, so please send me a message before purchasing. - Model Name: PITCH BOX - Color: Blue - Input Terminals: 1/4 inch jack - Output Terminals: 1/4 inch jack - Adjustment Knobs: Pitch adjustment knob Thank you for looking.
