Very versatile
I really like this wah-wah because it has a LED to display whether it's on or off (in a concert while jumping everywhere, this is VERY useful). It also has 2 wah-wah modes: a dirty 'cry-baby' style sound and a cleaner wah sound. The mode can be changed by a small switch on the side of the pedal, it's very nice because the 2 sounds are quite different.
The boost is also very good, although I don't use it so much.
