Born to obey the demanding boots of no other than guitar god Steve Vai – a guitar virtuoso and a true tone aficionado. This second version of the Bad Horsie adds a second Wah mode (Contour Wah). In contour Wah mode, two knobs, Contour and Level allow you to tweak the loudness and frequency of the Wah. You can switch between the Contour and Bad Horsie modes easily on the fly with a footswitch. A Bad Horsie and then some.
