Though I have not compared this pedal side-by-side with either a Dunlop or Vox Wah pedals, this is another great Harley Benton product that feels just as professional and well-made as the industry standards.
This pedal is heavy, solid, it gives you a good feel and you can rock it without any worries. Sound wise, I can compare it with the Wah sounds of two pedal boards I have owned (zoom and vox) and with the Line 6 M5 pedal (this emulates both Dunlop and Vox Wahs). The sound you can get with this unit is quite nice (even better if you consider the price). I would say it is more on the lines of the Dunlop Cry Baby than Vox (then again, I am not an expert). It is a great soulful Wah sound nonetheless. The frequency range of sound it affects is quite wide and it definetly suits my needs.
There are no settings or configurations available in this pedal. If that is what you look for, you may have to consider other options. If what you are looking for is ease of use, classic wah sound straight out of the box, do not look any further.
