I just upgraded my HX Effects to the new 3.15 (3.20 will be out fairly soon so you could wait for it.) I got several new effects to play with, some very good. They also made the way it works easier / better, and most of all the effects sound even better. Every time I upgrade this thing it gets better and better. I highly recommend the HX Effects for people that only need effects, like me. I love a good old tube amp like my Chupacabra, there is just something about it. Sure you can get modeler's and small amps to push, but just like cars you just can't beat a good well tuned big block. I think all the Line 6 stuff has a free upgrade, including the EDIT software that goes on your computer. Anyway it's worth the time to get the download.
