Wah Wah standard.
An input and an output jack.

UTILIZATION

Very very simple to use. This pedal is in place, it does not move a foot of each action.
It is in my opinion one of the pedals with the best touch. Personally, I have not seen No better wah wah.

SOUND QUALITY

Indeed very effective, it is taken very quickly to Jimi Hendrix . L I use with my Epiphone LP Std and a multi effects pedal BOSS ME 50. Since Boss knows tjrs not do wah wah, I still use a cry baby.

OVERALL OPINION

I used the nearly three years. S certainly the pedal is a little more flexible in mechanical but is Always a pleasure to use.
Very good value for money.
