The sound quality is very good, but it has a low DSP power. I mean for metal, rock, blues and this stuff you only need an amp a few FX and you are good to go, so for this music type it is a good choice. But if you want to play worship, or this stuff of ambiental and rock type music... it sucks. I mean if you put an amp capture, two drives and some reverb you have almost run out of DSP, imagine if you would like to go dual amps... you could ad some drives, some compression and you are out of DSP.
A very important thing... you can not assign a parameter from a drive (as an example, you can not on any type of FX) to a footswitch. I mean if you have a drive, and in the middle of the song you want to increase some gain by pushing a footswitch, you can keep dreaming. So it does not have that many features as other multi FX pedals ( like a helix, pod go, quad cortex, hx stomp etc).
Disapointed.
