Wheeew, I could write so much here.  This is the No-Nonsense Wah Pedal.  My first one lasted 25 years of steady use.  It died on me, and in a weak moment, I purchased a Behringer Wah pedal.  Wrong.  I can't describe my disappointment with the Behringer.  I immediately ordered another Cry Baby from Amazon, and doggone it, I think it's even better than the first one I had.  If you're looking for a Wah pedal, go ahead and spend the few extra bucks for the crybaby.  You'll be glad you did.
