Fretboard finish

[Novice]

Thanks for the help guys.
I have just finished my TL1 and am pleasantly surprised at how it has turned out, however I did have one annoying problem.
This problem was with the open B string that had a ringing, buzzing sound to it.
I Searched online and found a solution, place a piece of alfoil in the B string nut position and it worked.
Has anyone come across this problem and if so how did you fix it.

I agree with Wokka here. If you were going to spend money on just one upgrade, I'd say get a decent bone or graphite nut. Those plastic ones are garbage.
