G and A strings rattling on the fingerboard.

[Midgar]

It's mostly my G string when I play A, But it is also my D string when I play E

When I get into the music my G and D strings rattle...and it bothers me. How can I fix this issue?

You need to have your fingerboard dressed by a professional luthier. If you site down the fingerboard from the scroll end, you will see high and low spots.

[BananaKing]

How low is your action?

And how is the rest of your bass set up?

[EggyToast]

Yeah stick a yardstick against your fingerboard -- you should see a nice scoop along the length of it. Yours is probably bumpy.

[Greg Clinkingbeard]

lol. A yardstick isn't going to tell you much unless it's REALLY bumpy. I guarantee it's got high and low spots.

Most likely the above is correct. Or, your nut could be low. (don't be immature)

Try to slide a piece of heavy paper or thin carboard, like a business card, under the strings all the way up to the nut. It's okay for that to be low, but there should be some clearance. Not a big repair if that's it, but for either it or the fingerboard, you'll need a luthier.
