Watched the Christopher Schlegel videos on changing strings, put two strings on the 6th and 5th string and both now buzz like a swarm of bees. Both strings are in tune, even went to the ultimate scale finder under toolbox on fret 1-15 and both strings play all the notes, but the buzzing is overbearing and do not know what to do. Strings are 100% the same String gauge as the ones on previously 9s same exact brand Yamaha, it was a second pair of strings that came with my starter guitar. By the way I turned the peg by hand I do not own a string winder.
