So, I've noticed a small problem with my bass. My A string doesn't seem to have a very strong signal. It also makes sort of a buzzing/rattling sound, too. Though, I only notice that sound when not plugged in. Furthermore, when I hit any note on my E string, it's annoyingly loud, at least compared with the rest of the strings. Though, most noticeable when played right after something on my A string. What could this be? I was thinking about adjusting my pickup height, but would rather not if I don't have to. Could it be a problem with the pickups themselves? Let's hear what you think. Oh, and the bass is a MIM P Bass, if that makes a difference. Thanks.
