The Boss PS-2 Digital Pitch Shifter/Delay pedal is one of the rarer Boss models, manufactured in the late '80s and early '90s. Two full-fledged pedals are rolled into one, the PS-2 offers both individual pitch shifting and delay capabilities. It contains six different modes: 125ms delay, 500ms delay, 2 second delay, manual pitch shift, up an octave, and down an octave. Its knobs allow you to control the balance between each effect and your original signal, the feedback in your effects, and more.
