What about the iRig Acoustic Stage that will be available in April? Worth waiting for? What additional does it offer? I am REALLY a nerd on this stuff. I know other posters have said they're newbies concerning this electronic world but I'll put my lack of knowledge up against anyone's.
ETA: it's already out and MANY UU folks already have them in hand now.
Since Jan 18th, there is this thread that I'd started that's had a pretty active conversation, maybe this will help you:

But I have to ask, with whom are you competing for knowledge (or lack of)?
There's no contest here and we are all both student and teacher.
