I have an Ibanez V72 acoustic, I've had it for about 3 years and lately i've started having some problems with it.

The G and D strings buzz when I play on the 9th and 10th frets, any other positions are fine.

I've tried changing the strings, tightening the screws on the tuning pegs, cleaning the nut, cleaning the saddle and adjusting the neck and it still didn't help. Only thing I can think of that would be causing the buzz would be the fret wire.

Any other ideas ?
