Already described can not be simpler, since there is no knob to rotate in all directions to try to find a sound.
Goes very well with my Kustom Defender which has a volume control

Two points off for not always easy to operate (well mine is not very young so it just may be there)

SOUND QUALITY

Simply a very good wah.
I was looking for a wah wah for some time, and after a happy coincidence that I got it (gratos).

Used as it
Fender Tele - Digitech EX7 - Wah Wah - Palmer Preamp - Kustom Defender
I play mostly rock / metal, basically I wanted a wah to use the Adam Jones (Tool)

Both clean distortion that I like his sound.
Admittedly a little garish, but it does not bother me.
The effect is present, although progressive pedal (and no effect wwwwwaaaaaaahhhh wwwwwwwaahhhh).

A light breath after running, hit a small spot less.

OVERALL OPINION

I use it for a few days, as the title says, this is a very good wah who did not want to waste time turning knobs to find her drinking.

I tried a few before this one: Ibanez WD7, distos multi effects ...

There is another world, she'll stay long on my PB

The pros: the sound, solid
The -: the breath after running, sometimes difficult to operate. A good wah
