So I was playing along to a few Smithereens tracks yesterday (most of them are a half-step down) when I noticed that my bass began to rattle at the second fret on the A string. It just happened randomly, and it's been like that since. I tried tuning it back to standard but it still rattles. I thought it was the way I was positioning my fingers, but I held it the same at the E and D strings and they sound just fine.
Anybody know of a solution?
