Okay after moving everything back into my house i started playing and my Ampeg 4x10 (BSE410H) started buzzing along with me. I removed the grill and it sounded like it was coming through the horn. I turned off the horn and the buzz stopped. So, the questions are: Where can I get replacement parts and how much? Is this a repair I can do, and how, or leave it up to the pros? Also I live about an hour away from a ampeg serivce center, so take that in to consideration.
