What's the best solution to lower the action of an acoustic guitar?

My acoustic guitar is like this one.

best is dalhin sa magaling na luthier. di kasi yan basta lang sanding ng saddle nor bridge dahil puede maapektuhan ang tone pag kulang sa angle ang strings. worst case is a neck reset.

Depende pa yan sa condition nung top. Kung nagbbulge na yung top at hindi kayang habulin sa pagsand ng saddle, baka isand na rin pati yung mismong bridge na tinutungtungan ng saddle.

if the neck and top are ok you can just sand off the bottom of the saddle or nut, but do it carefully and slowly.  i don't think taking off 1 or even 2 mm of the saddle will affect the tone too much, but going too low will make the fret buzz.

measure the action on the 12 fret and on the 1st.  then determine how much material you want to sand off from the measurements.

its also a myth that adjusting the truss rod will raise /lower the action.  it does affect action but to a very small degree its job is not to control the action but to help support the neck from the string tension.

^What he said.

Also, take care to check that there all frets are even. Since you are aiming for lower action, it's best to make sure of this little thing. Hope you learned  a bit
