Hi. I bought a new LP Jr 2020, and when I play it, I can hear weird sound I didn't expect. It is like the sound from the piano's high keys(something different from buzzing). It overlaps with the normal sound. And that sound is especially heard a lot on the D string. I bought a 2018 model before, and I had the same problem(it was even worse). Because of that, I returned it. I want to know the reason. What makes that sound? Is that common? 이상한 소리.mp4
