This pedal is a gear or noise suppressor. There are four outputs: an input for the guitar, an amplifier and output to the input and output of the loop.
It is very solid.
It works with a 9V battery or adapter (not supplied grrrrr!)
I put the outlet 9 for ...

UTILIZATION

It's super simple! You turn a knob to change the type of noise suppression and is used in two other efforts to settle its Gise.
The manual is interesting because it explains how to mount the loop (in parallel).

SOUND QUALITY

I am really impressed with the sound! The attack is followed, no longer leave Feedback, more purring ... AWESOME! I was hesitant at first because Boss has a reputation average.
But here, the sound is met perfectly! This pedal does wonders!

OVERALL OPINION

I then in April 2006 and I am really happy! At first I hesitated with the Rocktron Hush but I preferred this one, I do not regret my choice! In addition it is a gift from members of my group who had tired of hearing my amp hiss all the time! This pedal is ideal for live and repeat them!
THE VERY VERY GOOD !!!!! MATOS
