Right, so I don't know anything - bear with me, please... Previously, my bass has been sounding supa-sweet, but recently I changed my strings and now there's this buzzing sound on the middle-three of my five strings. The only thing I know about buzz, is that you can adjust the bridge to raise the strings, but I tried that to the maximum (as well as to the minimum, since I'm not sure what direction is what) and it still buzz equally much. However, I've noticed another thing that seem to be correlated in some way... maybe... The top wire-coating on the strings have, on my previous strings, always ended a bit passed the ....stable? (the headstock-thingy, where the strings are fixed before they reach the nuts). You know, like the strings get one layer thinner at that point. But on my current strings, the B-string and G-string follow the previous pattern, but the other strings' top wire-coating ends right around the second fretbar - and these are the same strings that buzz! Coincidence? Causation? Is it something you know anything about? Are my strings weird, or is that normal? Not very nice on the fingers when I slide, that's for sure... Anyway, what else can I do than just raise the bridge? I've heard something about a truss rod, or something like that, but I have no idea what that is... Thanks!
