So you like it pretty well? I've been tempted to get the EZ ROMP pickup, but I don't really have any need for it. That doesn't mean I don't want it - it would seem pretty cool. Plus I don't have an acoustic/electric, and then I would.
BTW, I have a Roland Cube too ... kind of cool, but the Microcube is really fun to play with, and its diminutive size is a good match for the Rover!
I assume you're using the steel-string RO10? I have both that and the nylon stringed RO20.
