I plug my accoustic guitar into my Peavey modeling amp with a Dean Markley accoustic pickup and get no sound. I plug my electric in and everything works fine. What gives?

Thanks in advance

Some electric acoustic guitars need batteries. Make sure that it's not dead.. or that you have one at all.
most likely a battery problem.

Edit: I would get the guitar and amp checked out just to be safe.
Its one of those wooden rectangles with a chord sticking out the side. I don't see a battery compartment. Man do I feel dumb right now lol
