The review is difficult indeed. On the one hand the extremely favorable price has to be considered, as well, that the weaknesses (such as feedback) are principle-related and does not necessarily go to poor workmanship or manufacturing quality back. On the other hand I am, just because of the weaknesses (dynamics, noise performance, and especially feedback) become not happy with the part. Especially annoying: amp models from other manufacturers can be personalized with this interface is often not at all or only very limited use, because it immediately comes to extreme feedback. Here I would therefore recommend consideration at least the same in one (admittedly usually much more expensive) Analog / Digital to invest variant. Another note (which, however, will not affect the review has): Anyone who is not satisfied with the Free amp simulations, the manufacturer has to reach much deeper into their pockets. Here the principle is that software upgrades are sold in small modules (each amp and every pedal, each effect and other features, as more tracks for recording), the price quite add up. That should be aware of the buyer in the purchase. It is therefore necessary to compare thoroughly whether more expensive hardware (with conversion analog / digital) may not be due to the generous software freebies might be worth anyway.
The bottom line: to be able to exert some extent viable solution to off the other equipment. The existing restrictions should however be aware of.
