UTILIZATION

Could not be more simple, you set the time between the decision of the note and the beginning of the mute and the intensity of the cut and the sound cuts like magic when the lamp lights up (gradually to cut).
3-button simple and effective.
Personally I put the threshold to 3 / 4 to 0 and the decay mode and I can not reduction M'E, n used that sound like that without loss.

SOUND QUALITY

Incredible efficiency.
At first I said "yeah it's true that it is boring but the buit there are just turning the volume knob" and I order more awareness gained by knowing that I did not test VAIT .
Since I can not do without.
It feels to spend in vain but made this investment, it is worth it.

OVERALL OPINION

Uncompromising pedal that works very well and will remain in my rig as it will work.
Incredibly effective and does not change the sound (at least I did not notice) as some say.
I've had three months and she follows me everywhere, repeat, concert ...
It holds the road in all situations.
