I need help. I have an active bass, which I am and am not a big fan of at the same time. Anyway, I am experiencing a problem that I don't know if my bass is the problem or if it is my amp. Occassionally, my amp sends out a sound that is best described as, I apologize, farting. Now I don't know if this is as a result of the battery failing or the amp's speaker torn. Anyone have any idea of where my problem lies? Thanks.
