I play bass in a weird band that I don't really know how to describe. The soundcloud link is mostly just me and a drum machine because we don't have an decent recordings. Anyway this pedal is pretty sweet. It's tiny(about the size of an MXR box) and seems pretty sturdy. I think it sounds great clean, after dirt or before dirt which I have never had a wah or filter that sounded good before distortion. The controls are simple. It has a three position switch that selects a frequency range. It goes from very subby to sounding to more of a 105Q and the last postion sounds almost like a guitar wah but still plenty of low end. There is a slight boost with the wah engaged which doesn't bother me but it might bug some people. I think they should have put a volume knob on this thing. That's really the only thing I'd change about it.
