Great sounding multi effects and amp modelling. You can dial in any guitar sound you want.
Very easy to use and loads of options for tweaking the tone. You can edit even further when you connect it to a computer, and also load in IRs.
There are loads of how to videos on YouTube to help get the most out of this unit.
There is a horizontal line on the lower half of the display, as shown in the pictures. This was present when I bought it. It doesn't impact the function of the unit at all, you can see everything fine on the screen. I got used to it very quickly and don't notice it when I'm using it. Apart from that it is in mint condition.
