A quick and dirty calc indicates about 150mA for 12 hours draw on an AA alkaline, so worst case should be 300mA if the batteries are in parallel, not series (unlikely). So you’ll be fine with the 2A output.
You’re almost there and it’s looking good.
I like the utilitarian look. Have fun building this one.

Looking very good there, and at least you didn't have to cut all the way through the body to fit the speaker. And you have a built in effects unit.
