I may consider this actually now that I think about it. It's more inexpensive than a corona chorus. Hmmmm. Are the modulation effects on it pretty authentic sounding though? I've only had one multi processor before and it left a very bad taste in my mouth. I'm sure they've come a long way since though, that was over ten years ago.
Man, I haaate multieffects units. I'm all analog all the time...til now. The MS-60b is surprisingly organic, none of that synthetic sounding amp modeling, and a lot of their effects sound better to me than the originals. I'm not a filter guy, but I find myself using them more and more, simply because they are all very well done and can be combined in interesting ways.
I've been wanting one of those micro amps too, they look sweet.
