Maybe i am just picky. I am not trying to come off as a no it all as i do not. I was just wondering how
many other people have had this problem and if anyone has a fix that will not devalue the instrument. For now i just cut my own nuts
and leave the A a little high, but i don't like to do this, just seems the only real fix.
I've never had the problem either, seven different Fender P and J basses, going back to the 70's.
The fixes like strongarms make a pretty big change in the break angle. A difference between a low
nut slot and high nut slot is only a matter of thousandths of an inch. I wouldn't expect the break
angle to change by enough to make a difference. Possibly the slot is simply too low?
I mentioned earlier that pressing down the string behind the nut can eliminate a buzz. But that
could be because it increases the break angle, or it could be because it increases the string height
on the fretboard side of the nut. Like a seesaw - push down on one side, the other side goes up.
So you have to be careful to determine exactly what the cause is.
Each string behaves differently. The absolute minimum nut slot height for each string will be different.
The same is true for action height at some particular fret.
Some do make their adjustments that way, setting each string individually for minimun height. Others
use a uniform or graded height, with the highest string setting the standard for the others.
Is the A string slot very much higher than the others? Or are the other string slots unusually low?
This problem for me comes and goes, so many may not even notice. I play my bass unplugged a lot just for practice. It is to me at least noticable when pluggeed in, but not as much. I play mostly through my home studio and use headphones which means i hear every little noise clearly.
Even with headphones, or a low volume bass amp, possibly you are still hearing the acoustic sound
from the bass.
There are devices which can electronically retune a guitar. Many have complained that they could still
hear the original pitch along with the retuned output. It turned out they were hearing the acoustic sound
of the actual tuning from the guitar in addition to the amplified, altered tuning.
But certainly with headphones, you are going to hear things you might never hear through a bass amp.
