I use it for a month.

Very practical because you can play anywhere in the pieces are in charge usb, and then, with a gig, there's something to do! Take a headphone (but you can also plug it into a hi-fi ...) a jack and you can work quietly o you want your songs. As stated by another user, the quality of mp3 sound is good, you can increase / decrease the tempo without changing the tonality. on the other hand, it's true that the quality of the guitar sounds (including distortions) leaves dsirer.Mais really good, hack, one may make it sound a bit. The use of the device is very simple, which is a plus. And what comfort! before buying it, I plugged my guitar on a multi-purpose, itself plugged my computer o headphones I was leaving ... and this in an apartment with a kid and f3 of an.Autre one point, there is a function that removes the central part of the audio track (for working solo) but does not terrible I think. It PForm sound and still means something ...
In conclusion, I would say it is a useful working tool and trs qqu'il not have to buy that guitar to work or s'entraner. The report price is good quality, 199 and I think I would do without this choice problem
