For serious studio work, probably not every demanding user will be suitable, if only because the digitization in this Boss is not of the highest quality. At the same time, portable devices support only 16-bit recording, while professional comrades write 24 bits and more. As a standard, this boss encodes the stream in its own compression (HiFi (MT2) Roland/BOSS original format), which, no matter how spinning, means certain losses.
But that's all in terms of professional recording. For home, for family, it's a very, very good option. With a careful study of all its features and the right approach, you can make on it just wonderful, quite decent sounding discs. It has good effects, including guitar, user-friendly interface. Of course, I wouldn't edit the tracks, let alone make them.
