This is the standard wah. This thing sounds great! There are a lot of wah pedals with a wider range out there but if you are looking for the traditional wah sound, this is the way to go. No other company has sucessfully replicated THIS sound. Other wahs are cool because of additional features and for their own affect (yes that is the spelling I intended). I gave this a 4 for the lack of features. If you buy this, a try adjusting the pot (read the instructions). Most people do not know about this feature but you can really change the voicing of this wah wah.
