Some info on Freddie Greens guitars and action. Truth or internet fodder, you be the judge ...

"Action Height:
Action is the distance from the strings to the frets. Set the action as high as your left hand strength will allow. The higher the action, the harder you can strike the strings without fret buzz. This will produce more volume and let the guitar cut through the band. Typical "high" action will allow three stacked U.S. one cent coins (pennies) to be placed between the 12th fret and the low E string. This is about 5 millimeters or 3/16"."
"Note: As the years passed, Freddie Green kept raising the action on his guitar and eventually it was at least 10 millimeters at the 12th fret! Can't believe it? Look at some of the photos at
www.freddiegreen.org that show Freddie playing."
