Boss PS-5 Super Shifter

A fun little unit that does all sorts of weird and wonderful things to the pitch of whatever you choose to put through it. It lacks realism and is sometimes unpredictable. Shifting the pitch up two octaves makes a guitar sound like it's been puffing on helium. It has a whammy option where stepping on the pedal makes the pitch slide up and down. It doesn't sound like a whammy but is very cool none the less. The harmoniser option sounds very cheesy but is also a lot of fun.
