I use it for about 2 years with a Vintage AC 112. Robust construction, the wah is stirring. All works fine. However the latency between two patches is annoying when you want to change right in the song ... There is a hollow! The value for money is excellent, it is still the best in the world especially with two expression pedals. This pedal is also the most sold on the planet.
The manual is not enough explicite.Je will not go this choice because the effect of latency between two patches bothers me.
