It's a big wah very robust very simplistic, one input, one output, an auxiliary switch, it has a knob waving to the curve of the wah filter, which allows for a very discreet wah or a large WAH very sensitive, there is necessarily the curve which you need. It also has a switch under the pedal to activate and deactivate the effect.
We can connect either a 9V adapter or a 9V battery.

UTILIZATION

Operation is very simple because it's a wah to a knob we branch, you turn and go, simply turn the knob to select the desired curve and within minutes you have tamed the beast.

SOUND QUALITY

The effect is very successful, more like a cry baby that vox847 (the wah does not undergo distortion), I used an electric guitar stratocaster type, I have no loss of sound, a truebypass power!
It goes well avecd other pedal, or amp with overdrive.

There remains a slight distortion if we remain in effect very low, with a huge curve, and attacking the strings very hard, but it is not dirty, and you really have to want to get there.

OVERALL OPINION

I use it for a few days but it's an opportunity that have already experienced, and it still works perfectly, as what it's solid. the other model type of hellbabe Berhinger or daphon does not happen at the ankle, I carried my choice on the boss because, FW-3 level value for money is great.

I would not hesitate to use it on stage and I intend to keep it very long, the only one able to change my pedal would vox847

The only fault is that it may have to be ugly, and the fact that we should focus a bit to activate the effect (although, just put a little leg forward and it does)
