Hello I am new to UG and I have a question. I have a Jackson JS30KV King V and when i play octaves in the A and G string after the twelve fret it the G starts to go sharp, so i wanted to know, does this have to do with intonation if so how do i fix it, or is it because of the string i have on it right now which is 22p right now. Any answers is appreciated, thank you.
Sounds like intonation. You have to change the lenght of the string. If its sharp then the string needs to be lenghthened I beleive.
ok thank you
SETTING INTONATION: from icepoint...
Most electric guitars provide individual string length adjustment for setting intonation. Fine tuning this length insures that your guitar plays in tune all the way up and down the neck.
Using an electronic tuner, tune your guitar to pitch.
One string at a time, play the harmonic at the 12th fret and then play the fretted 12th fret note.
If the fretted note is sharper than the harmonic, increase the string length slightly until both notes register the same on your tuner.
If the fretted note is flat compared to the harmonic shorten the string length slightly until both notes register the same on your tuner.
Repeat the procedure on all strings until the harmonic and the fretted notes are the same.
