So I just bought a used sterling ray34 from guitar center that sounded great on all the frets except the first 3. The fret buzz occurs on all 4 strings. And it's not the kind of fret buzz that only occurs if you pluck hard. I can literally hear no tone out of those first 3 frets no matter how gentle I play. I was wondering if this calls for a truss rod adjustment or adjusting the action from the bridge with those little hex keys. If I do need to adjust the truss rod, which direction do I turn the truss rod? Keep in mind I want to keep the action low, just get rid of the buzz on the first few frets.
