It's a distortion pedal as its name indicates.
The guitar on one side, the receiver of the other and possibly an adapter in the middle.
Everything is clearly noted.

UTILIZATION

There are three buttons can hardly be simpler.
I just looked at the manual.
You turn the knobs, we listen, we find.

SOUND QUALITY

So it's a distortion pedal. I have not tried thousands, and I am not persuaded my favorite seller and he was not wrong at least not completely. Let me explain what she does, she does it well but I find it just when it wants to tackle the bourrinage intensive. Carcass too just the example.
on the other hand to Boost crunch from the amp on the Black Sabbath or even real distortion to the Maiden is really good
I use a Blackheart BH15-112 Blackjack with a Schecter Diamond Series or an old Epiphone Les Paul Standard fitted with a Micro Iommi signature.


OVERALL OPINION

I've had at least 6 months.
I have not known before a lot of distortion. That of Marshall VS100H I had before, a DOD Attacker.
It easily surpasses.
It is easy to use, it sounds good, it is not very expensive.
With esperience I have, I probably buy it back but maybe not first, I am looking for something more nasty.
