This is a step up from your standard Wah pedal. The strangely dubbed "Q" knob switches between six modes so you can choose the "fattiness" of your wah. There are lots of other Wah pedals out there (especially the Morley), but I just think you can't beat the original Cry Baby. If it was good enough for Hendrix, it's good enough for me. It's true that wah pedals are what make 70's porno music so cheesy, but they can be used for good as well.
