Hi Guys, Its been 6 month since i didn't change strings of my guitar. My higher E string got broke when trying to do bend. I thought to better change all the strings of my guitar. After changing the guitar string i'm getting a buzzing sound on lower E string giving a buzzing sound when playing a fret 3,2 and 1. I asked my friend to adjust the truss rod and he said leave it like that. Can anyone tell me is it ok to leave it like that or I've to adjust the truss rod?? I'm using a good quality of string i bought the packet of 6 in rs 350. It is an acoustic guitar.
