Watched a couple of demos , seems to me that is gives you that quacky , nasal tone you get when you leave a wah pedal on in fixed in one position . you can set the tone parameters and sounds like it has a touch of overdrive . I just use the wah if I want that sort of sound , turn it on and leave it set to the tone I want , only takes a short sweep to hit the sweet spot . It's up to the individual , but I don't need another pedal in the chain to cover a sound that I use once a night.
