I’ve noticed that with my Brazos acoustic
guitar (model BA-50);
I tune the guitar as normal, using
a good chromatic tuner, but then
play a certain chord, and it sounds
a bit out of tune.
So, open strings tune fine, but
some fretted strings go sharp.
Do you know how, when you check
the tuning by hitting the low E string
on the fifth fret, and then the string below
it open (A), they should sound the same (be in tune)?
Well, I will tune the guitar to perfect tune with the tuner,
then go check it with that trick, and some pairs of strings
will be right on, and others will not.
So, I am assuming the intonation is off, but how do you
alter that on an acoustic? Electrics have screws to turn, etc,
but acoustics seem unalterable.
Also, the action on the guitar is a bit high, not sure
if that is related or not.
The guitar is from the late 1980's. I do not believe
it is worth much, so I'd rather not sink alot of money
into it if possible, although I really do like the guitar.
I just came back from the luthier. He took a closer look at it,
and discovered some loose/raised frets. I did not even notice,
but then, I am not a luthier! Anyway, wouldn't you know it,
the frets with the worst buzz are the ones that are coming loose.
He is going to reset/reglue them, and it should fix the problem
once and for all, and I get to keep my guitar! Woohoo!
