What is the height of your strings at the 19th fret?
I think we usually measure at the 12th fret.
My first and fourth strings are about 1/8 inch above the fret (the fifth string is lower) which is fairly standard.
I adjusted the truss rod a bit and got it where I felt it was more comfortable without any buzzing. It always makes me so nervous to jump in and perform the technical adjustments.
Your braver than I am. Just had a friend who has played and worked on banjos over 35 years adjust mine. He made a very small adjustment and said he’d look at it again this summer after it settled in good to see if it should get more of a turn. He suggests a very small amount at a time then let it settle in and adjust slightly more, if necessary, later.
