The sound this box produce is mainly good. There are so many different settings and effects that the area here is too small. See a youtube review of it instead. To program the sounds are (to be a box!) quite easy and the possibilities are many. For me, the downside is to handle it in a live situation. It is way too easy to step on it 'in the wrong way' and get something completely different from what you intended. Maybe it is something one can get used to overtime but I have not yet made it. The only effect I so far have found not being up to the standard I hoped is the octave that I find to be, well not that good. But apart from that, it is a fun pedal that you can play with for hours...
