@Imactuallyadrummer hey dude! I am glad you posted this. This is a no judgment zone! First of, its great that you use a metronome! As you said yourself, being a drummer for sure helps with keeping time. The run was quite clean and smooth so keep on going! As for the buzzing, it might be a question of technique or maybe the guitar needs a bit of a setup, its a bit difficult to tell. maybe someone with a better ear than I could determine this better?
Also, if I can give you one little advice, when you are ready, I think you should use your pinky finger when you do this scale. It will feel weird and uneasy in the beginning but its going to pay off big time when you will need to get faster or more complicated stuff. So yeah my suggestion would be to impliment the pinky while you are practicing slow!
Other than that, great video, please keep on postng more!
