Alright, I'm new here, so hi, and how is everyone? Breathing I hope. Anyways, to my question, I have an acoustic (Tara is the brand) it's an old guitar, and I just got it fixed bc the tail piece was cracked, and the E string tuner knob was broke, but it's all fixed now, and I was putting on the E string and I was going down the neck of the guitar playing each fret and I noticed the 11th and 12th fret is making an annoying buzzing noise. I was thinking maybe it's just old and you can't really do anything about it. Idk, what do you all think? A little advice would be appreciated. :D

Thanks.
