Hi bet....Assuming that's your only buzz, its as Mac said and the 6 fret is a bit high on that side. It may not have been properly pressed, but the way to fix it is to file it. Its easy to take a bit off, but you don't want to remove too much, so use a VERY fine file. Frankly, you can use a finger nail file if you donn't mind a little extra time. file only the area under that string....not the others. First, tape off with some masking tape the area adjacent to the fret. Both sides of the fret.....This protects the fret board. File a bit and then try it. Stop when the buzzing stops. Its not hard.....REALLY!!!
