Everything has been said before.
It's a distortion pedal with a metal type preamp lamp to warm the sound.
There are 6 knobs:
-Gain
-Middle
-Scoop (frequency corrector)
-Level
Hight-
Low-

The case seems quite fragile, but it's still not a case beringuer: you can make the stage that you can not jump feet join the switch (and again) ...

UTILIZATION

It took me quite some time found my sound.
No manual but it will be good going as long as you know what are the knobs.
The gain adjusts the rate of distortion.
Allows the scoop to dig the sound and open a wide range of sound
After we find the three-band equalizer very efficient (just turn the knobs to realize it). It's really impressive
The level can adjust the sound to light or sound of your other distos ...

SOUND QUALITY

I use this pedal with a jackson dk2-s equipped seumour ducncan TB-4.
I have an amp like H & K Matrix 100.
I was amazed by the wide range of sound offered by this pedal. This thanks to the equalizer very effectively supported by the function scoop which opens new doors.
The sound is warm and round.
The headroom is incredible. You can play most styles in extre like black metal with no problem.
The sound is far from being synthetic it is not over mesa and company. But it is far from Technology Modeling believe me.

OVERALL OPINION

J'utlise this pedal for 2 months. I had a hard time adjust my sound (I have been very good jms: /) but once set you will not tire.

I referrer to choose.

Every time I recommend you try the metal muff electro-harmonix is ​​cheaper is very interresting.
