I'm biased, I have 6 other Mooer pedals . . and . . not only do they function well but they're just great for the price tag. I've had them all for some time now and never any problems with them working, and this one is no exception!
I've rated this with an all 5 stars in each category, simply because not only is it a good automatic wah pedal, but if you wind the "Q" control right back, (the wah depth), you can get some really nice Trem/Vibe sounds with it too!
The controls give a very wide range of wah options!
With a switched high/medium/low signal peak, large central rate/speed knob and a smaller range/sweep control too. The "Q" is equivalent to a "depth" of the effect - to my ears.
Also . . .
With the "Q" set to zero, and the range full on, you will find a Trem/Vibe like sound without the wah tone variation. The rest of the switching works too, to provide an interesting range and addition to this pedal!
I actually use it more for this than the wah, which is good enough already, in its own right!
Well recommend all the Mooer range if you're looking for an excellent price tag and reasonable effects. They are all well made cases and sturdy enough for gigging, but with the added bonus of a small footprint on your pedal-board!
Don't let the size fool you!
