With my current headset mic my trumpet sounds kind of muted. I'm not really fond of music theory but I think what happens is that all the harmonics aren't captured.
As a result, I'm looking for a microphone! I don't need an expensive one, just 15-25 euros because as long as it's actually intended for (wind) instruments it's going to be a huge improvement.
I don't have any experience on this matter so I thought you guys might have some suggestions.
