So I purchased one of the Fender starter packs back in 2010, and have been teaching and practicing on my own since. Recently, after a three month hiatus, I came back to my bass, tuned it up, and I now find that when I dig in hard on the A string, there is a loud, atonal buzzing noise coming from the area of the pickup/bridge. It occurs mostly with an open string, but to a lesser extent when I fret on the lower half of the neck. Has anyone else had this issue with an Affinity series? I know they're budget, but mine has, to this point, been rock solid for learning on.
