My First Build the GR-1SF

[DrNomis_44]

Worked out the most part of the buzz! It did have to do with the nut!(really didn't think it did, sorry Doc!) The 'A' slot I cut was too deep and the string was vibrating on the first fret 😖 So I have filled the spot with epoxy and will have to recut the slot... Hopefully that fixes the most part.
My husband thinks the secondary roller is moving a little too much, he is also going to price me a Bigsby B70

That's alright mate, at least we know what the cause of that high pitched buzz was, you're in a position to do something about it to sort it out now.
