I've got a new Bach TR650 trumpet recently.
On the first valve cleaning I've notices there was a small burr inside mid hole of the first valve (link with picture is below)
I was able to remove the burr simply by my finger. But unfortunately the small bump inside the small circumference (inside the valve) remains. It is like half millimeter high and 2 millimeters long.
So my question is what do I do next?
Or more specifically, have you seen something like this before? Are there any negative impacts of such a thing on sound etc?
Can I just leave it like this? Or should I worry about replacement?
