I just changed the strings on my strat, I've only done it myself a couple times, so i didnt do the best job. Now all of a sudden The top 2 strings buzz while im fretting, i can play them open with no problem though... I think it might have something to do with the strings buzzing agains the fret right after the one thats fretted for example, If I was playing the low E string with an A note or fret 5, the 6th fret would be buzzing, but I could be wrong. Please help!
