from Downey California

My cousin bought this for me for graduation, it has cool distortion/overdrive options and a whole lot of other effects. It also has a wah effect controlled by the big pedal also called the expression pedal on the device. The wah effect is really good if you aren't a crucial critic. Overall it is really good, but I can'y really find out how to program effects to the three pedals it has. It is also not metal constructed like other pedals, so try not throwing it around even though you might never even think about doing it.
