New Boss ME-25 has a bunch of features and seems like a pretty good bang for the buck. It looks easy to use and works like a stompbox. There’s built-in Sound Library which gives you instant access to dozens of classic and modern effects. There are COSM amp models onboard, plus Super Stack and Phrase Loop functions.
Some additional features include: Can functions as a USB audio interface, built-in AUX input for jamming along with external music devices (MP3/CD players, etc.), runs on six AA batteries or AC adaptor, Cakewalk SONAR 8.5 LE software included, Free downloadable Librarian software.
I have a Boss ME-50 that I use for traveling or fly-gigs and it does a nice job of giving me everything I need in a small easy to use package. I would think that the new ME-25 should be as good if not better than the old ME-50 model. More toys (tools) to check out..!!!
