Then it is a distortion pedal (hey it in my opinion it is already known) brand harley benton for the sum of 24 euros ...... pathetic.

there level settings (volume) mid (medium) low (bass) and high (treble)

well it's simple right?

USE

The settings are simple turning and looking at doing that ca ..... it's as silly as AC and 2 minutes was the sound slap.

SOUND QUALITY

So I was looking for a fairly heavy sound dirty qi do all tremble ........ and I found that sound. and yes this pedal is perfect (I'm of metal) and on each bass has a different sound (tested with a 374 yamaha rbx an Ibanez btb a ibanez atk bc rich warlock and .....)

I love this pedal all sonoritées are good.

NOTICE GLOBAL

I use it for a month and I can not past me.

the price / quality ratio is surreal.

I would do this choice with his eyes closed.
