Hotone Wong Press Volume Exp Wah

I ordered a B-stock pedal, the Q knob did nothing, so I sent it back and got another one brand new. Q knob still does nothing!!! I got in touch with Hotone support, they say yes it's subtle and Cory wanted that way. But hey this Q knob does absolutely nothing believe me. Also tested with white noise sent through the pedal and did spectrum analisys, nothing moves. So I don't know what's happening here. Other than that I quite like the pedal and the features. Maybe it's just too small, right your average smartphone dimensions, you need to get used to it. Also if you have a pedalboard with bars (I have a Palmer) it doesn't reach up to three bars but two and a half, so it's not the best to have it stable. Nice built quality, velcro sheet already included in the box.
