Circle K issue - buzzing, and it's not the frets, nut or hardware
The 3rd and 5th strings (A and B) make a very faint buzz. More like a pfpfpfpfpfpfpfpfpfpfpf sound. It's not fret buzz, rattling saddles, loose screws, etc. I swapped tuners and the same 2 strings made the same buzz. I then tried D'addario and TI strings and the buzz was gone. My first guess was that the trimmed end was rattling in the tuner post. I tried trimming a tiny piece off the end, but that didn't help. My guess is that the strings are defective.
Any other ideas? I emailed Circle K, but they're at NAMM and probably swamped with emails by now.
