…a banjo is out of tune?"
I just put new strings on my banjo, swapping out a heavier set for some JD Crowe medium-lights. 10-11-12-20-10. After stretching them out I tuned my banjo. As usual, I started with the middle G. When I was finished I had this, starting from the fifth string: G-D-G-C-D.
Wait a minute. Shouldn’t that be G-D-G-B-D? When my Snark tuner said B, the banjo sounded horrible! I tried another Snark tuner, brand new just out of the box. Same results G-D-G-C-D sounded good, with a B it sounded terrible. I even made a short video to post to show you exactly what the problem was. As I was reviewing the video, the devil who lives in the details suddenly revealed himself.
When I tuned the middle G, my eyes focused on the G and all the little red & yellow bars. I never noticed the # next to the G.
I had tuned my banjo to G#.
And that’s how Earl did it!
