Terry, interestingly, I listened on my phone and didn't find any distortion, in fact I thought it was one of your clearer vocal efforts ...
While you took the earlier advice and used the harmony more sparingly, its volume could still be a little lower ...
I think those of us who use the VH - on board or external - would agree that 'less is more' and most times all that is needed is one harmony voice above yours ...
Keep at it ...
