Harmonica Playback Sounds/Sound Font Issue?

I am using whatever sounds came with MuseScore but the sound I use the most for my scores is for the 16 Hole Chromatic Harmonica. However, the sound of the notes between C4 and F3 sound a little strange, as if there was too much reverb?

From F3 to C3 sounds a bit better but the lower register could be playing tricks on my ears.

I don’t know if there is something I can do, or whether it is important enough to report as a bug?

Thanks in advance for any insight you can provide!!

BTW - I have been recently using MuseScore 3 exclusively and in my experience, it is a HUGE improvement over previous versions. I really noticed how much better it was when I transposed a song with lyrics. In the past, depending on the key, it may have required an adjustment of the lyric spacing among other things. Now, it is just one click and I’m done!!

Great job, thanks!!
