Hi Ken,
unfortunately I don't sing, so I've never tried it.
I really only use mine mine for soundfonts.

Somewhere floating around I have an old mic, if I find it , I'll plug it in and see if mine works.

Fortunately it's nearly XMas, so hopefully your son can help you sort it out.

best wishes
Rikki
