So anyways I got a new acoustic/electric guitar and there is a battery thing that slides in and my little brother messed with it and put the battery in backwards. Could him doing this screw it up because yesterday it worked fine on my amp and ever since he did that it doesnt work anymore. It is not the amp because i tried my other guitar on it and it worked fine, I was thinking putting in the battery backwards might have burned up the stuff inside, Please give me info!!
