Im looking for something cheap and only interested in piano tones really, is this something I should buy? I've heard good things about it, I'm playing in a punk band, so it'll be every now and then, nothing concert hall quality just wondering if anybody has one and would recommend it for occasional stuff? Also how's the organ tone on it? Any good? I have a sound module for that but would be nice to have a decent organ tone as well just to play around on without hooking up stuff.
