Lakland 5501 weak A string

[lukiluk]

Hi,
I have purchased a used Lakland 5501 with stock mk1 pickup
A string has weaker volume and no punch compare to others strings.. The setup is right.. Is normal for these pickups?

Check to be sure the string is well seated at the bridge (i.e. witness point.) I had a dead A string and all I had to do was push down real hard between the bridge and the string mount (i.e. set the witness point.) My bridge piece had also lowered from playing so I put a little loc-tite on the screws and reset it too. Some basses are prone to the bridge pieces dropping down after being played a lot. Both of my P Basses have done it. A little loc-tite works wonders for this problem.

I changed the A string ... But it continues to be weak..
Maybe it's the pickups
