That's a nylon string guitar, right? Nylon strings can be problematic! :) You might need to stretch them & be patient as they gradually settle in. Please check this video lesson for tips on dealing that situation.

Best of success with it! Let us know how it goes or if you have any other questions.

I think tuning keeps getting better, but ive noticed that there is a minimal intonation problem on g string, open string is not perfectly related to 12th fret, ive calculated frequencies, there is a 2 hz difference when i double the amount of open string, other strings are better in this regard, ive researched a bit and people on internet say that this is normal no guitar is perfectly intonated, no fret is perfectly intonate according to a=440 there is always a minimal difference, is this true? at first i didnt notice any difference in sound, concerning the g string, but now its psychological and i think g string open or not sounds not as good as first two nylon strings, its probably normal but i need affirmation on this matter just to ease my mind, is g string a little thicker (maybe) then the first two nylon strings? can you tell me are these frequencies normal (a fret on g= 220.6 g 12th= 394.4 g open= 196.0)
