Muted open string
Just drop tuned to D standard. I am having two issues:
1. The G string, sounds a tad bit "muted" when played open
2. I'm getting a tiny bit of rattling on the C string, when played open.
I don't recall having these two issues when the guitar was in standard tune. And I don't hear anything when fretting the notes.
I have added a bit of relief to the neck, to no avail. I even raised the action, which did not help either.
It is only happening on those 2 strings. Guitar has a FR on it by the way, any ideas? Action is around 3.5mm measured on the 12th fret, low D.
