The Joyo Multimode Wah is a 2-in-1 Wah AND Volume pedal. Easy to use simply press the toe side down to click-activate to get crybaby-esque tones. Two modes switch to choose whether you want regular bypass signal when wah is off or if you want the pedal to act as a volume pedal. There is also a volume slider to control how much volume cut you want in volume mode. In addition, the Wah tones can be adjusted with a mode knob that you can cycle through as well as a fine grain Q control which adjusts mid frequences. Turn it up for more quack, down for lower resonance. The pedal features RM shielding, a Green Led when active. Constructed of a solid metal housing, this small wah feels solid and stays in place. Space saving footprint of 16cm x 6cm. Not too small, just right!
