This is a really great little unit - very high quality. Lots of great sounds, lots of room for expansion. Great A/D and D/A conversion. A good solution if you need a reverb unit with a little more flexibility than a pedal or amp can provide. These originally sold for over 700 dollars when released, but they blew them out when they were discontinued a few years ago for around $300. Mine's in basically mint condition, a little rack rash. I just have no use for it. $140 shipped to ya door, if you're in the cont. 48.
