I'm posting this because about a month ago I bought a lovely epiphone EJ-200 electric acoustic, which has a lovely sound & everything but the batteries keep dying after a week max., so I wondered if there's something wrong or is it really meant to be this way as I love the sound when I play it on my amp?! The batteries are 2032s, but I wondered if I could get something that would last longer? Cheeeeers.
