Feature:
It is a volume pedal and a wah pedal. The sound booster can be turned on and off by a switch at the side, so players can choose if they want to have it. Pretty much saves the cost of an extra volume pedal.

Quality:
It looks and is durable.

Value:
This pedal is cheaper than other models I saw at a similar shop which did not have the volume control, just the wah. The sound is also identical.

Desirability:
Smooth and usable, a double featured pedal. Most will want it.

Sound:
The sound seems good in different setups.

Ease of Use:
Rock the fott mechanism back and forth for wah and volume. If you want the volume boost, press the button on its side, without needing to bend over. To change to volume, push the front end until the LED turns off. To wah, repeat. Seems pretty simple.

Support:
I only went for help once to deal with feedback. It was my power adapter that was the problem, and they changed it for free.

Overall:
If it was stolen, I probably would buy another.

personally, put this thing in this order for it to sound good, guitar > mr. crybaby > distortion > amp. don't put it in between your distortion pedal & your amp, it sounds bad, do it the way I said for it to sound good.

Not to long after I got one it got all scratchy. So I sent it in and they put new pots in. Two weeks later it sound scratchy again. I just use it as an on off switch now basically.
