I ordered the Boss BR-80 mainly for practicing at home without the hassle of setting up an amp and effects and so on. Quite simple, guitar in, headphones out, wide variety of backing tracks and recommended guitar tones, plus you can also use your computer to transfer your favourite play along songs. The e-Band function is great. However, it took a lot of time to figure out how the multi track recorder works, and then setting up the percussions and all is a big hassle. Moreover, the live recording function with the condensator mics sounds good, may even work in a small home studio, but didn't quite work as expected to record a live jam sessions. Additionally I ordered the boss adapter so I don't run through my AAs.
All in all a good product for guitar practice.
