I have Montana 104N Acquostic Guitar.
I purchased it in January.
I have been facing this particular problem....i have already broken 2 strings while tuning my guitar.
Actually I took out all the strings to clean the fretboard and then re-screwed it.I broke G string and then yesterday A string.
Is there any problem with the way iam tuning it.
Do lemme know.
Anyway iam replacing them with karuna(the only spare i have right now).
