Hey how goes it.
I'd love to have one to mess with. I have had a multi processor (still do) but, the more I learn the less I use effects. What I really want is a kick ass mic, a kick ass pre amp and an awsome compressor. I mostly use delay, some times a slight chorus, and a little reverb on occasion. For those I use software. So With me, and I'm sure many people here (strugling to get a decent setup on a budget). A kick as multi-processor is down on the list a ways.
There are some things that a processor like that might come with that are hard to find as a seperate device (that is worth a shit).
and I have used much lesser models for live sound with pretty good success. The thing for me is that there are so many effects in these processors that have no practical use. When it comes down to it I want really good quality in the things I always use.
Buy it from a place with a no questions return policy and spend some long nights alone with it.
Good luck.
F.S.
