Wah wah pedals which when touched.
The board operates a suprieur crmaillre that turns a potentiomtre Tone of the acute to the grave. The action is not large but trs trs sensitive actually.
Crachouille the pedals a little from time to time so I disassemble the rgulirement him a shot to bomb in the knob and leaves.
I noticed that often in the tranport of pdalier, the switch locks into position "no sound". In the beginners I was looking everywhere o the problem could come in my chain but now j'enclenche once the pedals and I found the sound by a miracle. It is insignificant as a stepfather, but even when I had a few cold sweats at the start when a concert the sound was gone strangely. I've even seen in the emergency bypass directly connect me to my pdalier live in the amp.
So for those small inconvnients I put 5 / 10. Could do better.

UTILIZATION

Directions: you put your foot on it, you apply pressure to the front, which has the effect of activating the switch and dclencher effect. You move your foot from front to rear convenience (without forgetting itches course). Forward is acute, to the rear, it's serious. It's like they turned a knob your foot in rgl Tone gives a frquence.
Wah-Wah that did. In fact it's funny, when you activate, you find yourself making wah simultanment with your mouth ...
It's quite enjoyable as effects finally ... the wah wah's foot!

SOUND QUALITY

For my part I that the essay so I did not compare pure again.
It is true that the effect seems to me well, I used to Rhythmic just plain funk and especially for the distorted sounds with Santana or Hendrix Ibanez Tube King or she wonders. For me suits me perfectly.
The BMOL now: dterioration bypassed.
I'm not a freak true bypass, away from because I Whereas many famous guitarists have recorded our solos prfrs Despite this inconvniement.
But it's true that the pedals you do not eat a lot of treble in your circuit.
Okay when used only say to me, but another couple of pedals without true bypass it, too, has come dterioration gives you a nice sound of your guitar . Try plugging in you live on the amp and you tell me the news. You are wasting bandwidth, especially in the acute but also a bit in the bass.
The solution exists it is true: you can change this by changing the switch pedals and making a sort of bridge on the PCB. Number of tutorials on the web you explain in detail. But when same, although HP has ... also shows that a brand is aware of the problem and does not proppose a version of the pedals with the change in SERIES for a reasonable price. As a result, many users turn to other brands forcment Chres more. L I confess I do not understand, the IDE seems to me simple yet ... or there are constraints of marketing or technical m'chappent ...

OVERALL OPINION

I use it for 13 years and I love the sound and sensaton it provides.
Today, I plan srieusement to change to one that would not inconvnients above. For now I have not found that.
It is not so I trs CHRE Whereas when the same report quality price is right.
With the exprience and with money of course, I would choose over a MODEL.
Come on, I put 7 / 10 as it is when a same legends.
