The WAH/VOL pedal delivers both an excellent Wah response tailored for BASS along with Volume function and all in a small foot pedal. It doesn't take long to get the feel of this unit, It's incredibly easy to manipulate with your foot to get the exact wah tones you want. It is very compact and much shorter than a standard Wah or Volume pedal, it sits comfortably on most pedal boards and can be used in either clean or gain settings.
