It's simple to do in person, kind of hard to explain over the internet. You said the buzz was on the low E string, do you mean when you hit the open E string or in a certain fret position? First check the neck relief, there should be a slight amount. If it looks good then proceed to the bridge where without any tools you can detune, turn the adjuster knob counterclockwise to raise the bridge. Keep an eye on how much you turn it so that you can put it back to stock at anytime. Retune and check for fret buzz again. If the neck needs to be adjusted I could only imagine it being a quarter turn at the very most, but I would wait until the neck settles before doing that.
