The pedal seems robust and well built.
The sound of wah mode is not exceptional, but acceptable.
Big advantage is the Q-knob and tone switch which, in contrast to many other wah pedals of this price, allows us to fine tune the sound.
However I was not satisfied at all by the pedal behavior at the volume expression pedal modes.
In both cases the volume/expression parameter changes very abruptly, preventing from nice "fade in" effect.
To be honest I expected more from these 3-in-1 solution.
Since only wah mode worked for me, in my opinion, it would be better to buy just a wah pedal for this price.
