Well, I have a amp that really sucks (no earth, a hell lotta feedback, no Dist. switch, etc...) so I thought that this software was a good way to replace it because I don't have a lot of cash to move to better amp .(but hoping to get a Laney LX65D or a Peavey Vypyr 30)

So is this a good buy? And can I use my normal PC microphone input to use it?
