im sure its the machine heads, theres also a fret buzz on the low E but i dont want to do any filing
Well its the bridge a strat trem bridge tends to be a little more complicated than tune o matic ones to raise the action onyou see those peices in front of the holes your strings come out of on the bridgeThere are 6 screws you can use to adjustone for each string so just raise the low E up a little at a time then check to see if it still buzzes or notquick tip the closer the buzzing fret is to the nut the higher you will have to raise it.
