I have a violin made in 2021 but I've had a couple of months.

If I bow lightly on the open G or bow hard it sounds beautiful. But when I play any note on the string lightly it sounds odd to me. But if I play the note really loud the string sounds better. Much better. My other strings don't have this issue. I switched to Pro-Arte strings but it is still doing it. I took off the practice tapes my teacher put on and it still sounds odd when playing notes on the string. I have tried different bow speeds. The only thing that seems to make it sound right is playing notes on the G string loud, like Piere Holstein plays on his YouTube videos. He seems to really dig into his playing.
I checked the bridge. The feet are flat on the violin. I looked at it super closely with a flashlight. It is at the proper 90° angle. I did put Wittner geared pegs on it myself and Wittner tailpiece with 4 string adjusters on it myself as well. When I installed the tailpiece I put tape up against the feet of the bridge to mark exactly where it goes when I re-installed it. So I know the bridge is where it was when I got the violin.

Well I'll be dang, I was just listening to Piere's "Learn to Play Raglan Road on the Violin" here: <a href="
