Wha effect with a knob (frequency I think). Beautiful copper color, words of Black Frost Way To Blue Alice In Chains (listenable on the album of the same name) below.

UTILIZATION

One branch is activated, you hack the knob located on the right side (about 12 for me) and it explodes!

SOUND QUALITY

So here is what really makes the difference. If you are not looking for his Wha garish but well-defined medium and this pedal is for you. The knob is really effective to shape at will curve effect.

OVERALL OPINION

I used for a while, always with the same pleasure.
The only problem I had was a fault (ground?) When plugged into my "dc brick". Once battery powered (9V to place in the compartment just below) the problem was solved.
It may seem expensive but frankly it was worth the money.

Wha pedal just perfect both aesthetically sound level (pedal copper on a pedalboard it does!)
