By the battery i mean the one that comes with the 4 band EQ on the A/E bass. Its not lighting up and i dont know if this is a good thing or a bad thing. Usually if LED lights dont come on, its a bad thing. In regards to the buzzing, it is coming from the bass itself. The strings really are difficult to fret and my fingers keep slipping.
Another annoying thing is that i dont sound like a bass player, rather i sound like a lead guitar player who just plays a deep sounding guitar. :(.
