There's two great things about this. First, there's no clumsy switching, the effect kicks in using a sensor on the spring; it feels great is very intuitive. Second, it's got a really tasty thick, juicy wah tone that's all sorts of awesome. This iteration of the Bad Horise wah adds to the original Bad Horsie by adding a contour for voicing options. If you run this with the contour disabled (switchable), the dry signal is boosted which is handy for a simple solo boost.
