I am starting to get worried ðŸ˜, I just got this like 3 days ago. And today I decided to clean it (with a damp sock like its not that wet and not that dry), after cleaning it, I noticed this faint curve line, and I started to get worried since the opposite face is just fine. I also did the sound check, and it just sounds identical to the other side.
Please help me ease my mind ðŸ˜
I hope the faint line is just clear enough to be seen by you guys.
