Great pedal, very durable, works with my keyboard psr s770, for volume, modulation, pich bend and many more functions. I was a little disappointed with the wah on guitar but it has nothing to do with pedal but with my keyboard. Because you can't just add wah to any guitar voice u need to select a filter for the guitar that is pedal wah control which doesn't sound as good as regular distortion. Sorry if I'm not being so clear I don't know how to explain it without looking at the keyboard. Anyway the pedal is very good don't take my complaint into account it really a 5 star I just gave it a 4.5 because of my keyboard. l would recommend it to a friend.
