12 string accoustic
ibanez s520ex with black outs and an original FR locking tremolo with a custom neck, it's fucking sexy.

all of them are having inconstancies in their frets.

if its tuned 100% perfectly...

you know e a d g b e

by about the 5th fret, it's sharp or flat.

the harmonic on the 12th fret and playing the 12th fret is 1/4 a step off ATLEAST

can this be fixed? how much would it roughly cost?

Tune up - 40$ - any music store

Intonation problem. Could be fixed by changing string gauge, adjusting action, adjusting the truss rod, moving saddle closer/farther from the nut slightly.
First I'll ask you, at the 5th fret is it sharper or is it flatter than it should be? Let me know which one, use a tuner if you have to.
Also, how high is your action? I assume you don't have extremely high action, but sometimes if your action is too high than the excessive pressure needed to fret the string properly will result in a sharpened note. Is this just happening on one string, or many? You could definitely bring it into a shop, but it's possible to work on this if you know what you're doing. Please don't adjust the truss rod unless you know what you are doing though!

EDIT: I just sort of skimmed through what you said and didn't read the whole thing. This applies to the acoustics ^

However, the electric will be (should be) easier to adjust than the acoustic. I'll google that model and try to let you know how you would adjust it, when I get a chance.

Are the inconsistencies the same no matter what string? If it differs, lets's say the high e is way off on the 12th fret but the b is almost fine etc, then it's probably the strings thickness that's uneven, so try changing strings. I had the same problem when using the original strings on my electric, getting new & better ones solved it.

Intonation is something you can do yourself on an electric, all you need to do is turn the screws that adjust the string saddles and increase/decrease the distance until the harmonics are the same pitch as the frets at the 12th and 24th frets. Intonation needs to be changed slightly if you change the size of strings or tuning, it isn't much harder than changing and tuning the strings.

vouch. depending on what type of bridge you have, it should be easy.

temp change gettin ya? colder dry air is screwin with my banjos and fiddle already. thankfully my mandolin and guitar are impervious to this.

All of this is done in a simple tune up, if you're a noobie and don't want to screw with your guitar yourself (I've been playing 5 years and refuse to touch it myself), it's just around 40 bucks lol, get it done, they will fix it right

this.
