«  BETTER THAN WHAT IS SAID »

I will pass on what has been said before.

UTILIZATION

Contrary to what is said below, you can obviously get rid of the count (they are still not mad at Line6), just 3 minutes to hack the device to understand (or read the manual!).

It works like any looper, it is accurate, easy and offers the advantage of either the sampler or the guitar mic which is great for use vocals / guitar (a pr button to switch between the other)

In addition we can separately equalizer singing and guitar ... which is great too!

SOUND QUALITY

For quality sound, it makes the case pr of small live (pub) but it will never be worth heads tube amp!
I personally played the acoustic Gratt and I never used the distortion.
And contrary to what is said, too, can have the pure sound of Gratt bypassing the amp simulations.

OVERALL OPINION

It is a small bracket that makes his job for a fair price.
Very beefy must throw a building to break it.
And with samples of its banks and it's fun, for work at home.
The looper function is perfect, and the micro switch vocals / guitar is unique and welcome!
