Hey @Cameronjake welcome to the forum my friend! Glad you’ve joined us.
I’m re-posting @Slim’s reply from your other post here, so other people who find this post can see it:
I don’t think Horner’s quality control on the new Golden Melody’s is quite up to snuff. The cover plates often aren’t airtight.
I’ve bought a couple Thunderbirds with hole 1 issues, one the rivet was loose, and one the reed was actually broken and made no sound at all!
@Slim’s advice is spot on (as usual.) But you should be able to play it moderately loudly without a rattle. If you have to play it SUPER quietly in order not to rattle then there’s an issue. LMK.
