I'm at my wits-end here folks. When I received my new, amazing, gorgeous Ibanez RGD3127 a few months ago, I noticed an odd metallic ringing sound whenever chugging, palm-muted, on the open low B string. That's the ONLY time it happens: when playing the low B, open, with palm mutes. No other string or note, fretted or open, palm-muted or otherwise, makes this sound. At the time, I didn't much care, because I knew I'd soon be swapping all the electronics and pickups. I figured the issue would disappear. Well, I've now swapped all the electronics and pickups (and strings), and the #@$! noise is STILL THERE. Have a listen, and between the low B notes you'll here a bizarre metallic ringing: https://soundcloud.com/guitar-answer-guy/weird-metallic-ringing Hear it? WTF is that? What could be causing it?
