Synthy, deep sweep.... this pedal has for sure a lot more features (I'm too lazy to name them). Used by John Frusciante from The Red Hot Chili Peppers. He showed us all abilities of this great pedal. A lot of us bought it just because John is using it. I choose Wh10 not just because Frooosh is using but also I heard that it's one of the bests wah pedals on this planet. Great for guitar and also fantastic for bass. Extremaly good pedal but with a very bad price.
