I popped off the entire nut and sanded the bottom a little bit at a time. . This lowered all the slots at the same time. I found that the radius was fine, it was just too high. Now sure, With nut files I could get individual accuracy done to .001 but, I didn't want to buy nut files at this time. My high E needs to come down a hair...but my intonation did improve as did playability.
Just my 2 cents...take it for what it's worth.............uhhhhhh...about 2 cents worth
