Gregg uses 3 Pitch-Keys to switch between E-Standard and DADGBD/DADGAD. He has them on 1st, 2ed and 6th strings.
You may note he uses 1 and half twists to raise piston.
Pitch Keys can not be mounted on adjacent strings at the nut. The second one need to be positioned close to its tuner.
In my case, I wanted the ability to choose Drop-D or G6 tuning, so I have a Pitch Key on the 5th and 6th strings. The 6th string Pitch Key is positioned at the nut, while the 5th string on is positioned near the 5th string peg.
It was not trivial to install the Pitch Key on the 5th without the stability provide by nut. After 6 tries I finally got it. I had to retune all 3 strings involved of course, but it works nice now..

I was hoping to see him use them while playing a song. I was thinking of how Earl and other banjo players use their D-tuners. With the advent of electronic tuners, it seems like a lot of effort to save a few seconds. Now to do this, you need some kind of quick tuners:
-1962 Martin D-21 -1950 Gibson LG1 -1958 Goya M-26 -1974 Yamaha FG75 high strung -A number of banjos, mandolins, Autoharps, ukuleles, dulcimers, mouth harps, a Tele clone and various other stuff. -I own a fiddle, but only play it when Maggie and the cats are all out of the house.
Well, with the above positions in 3rd image you'll note that there is very little support from the 4th string for the stabilizer. The 4th string is simply too close to the 5th string to be effective.
This caused tuning problems. Operating the 5th string Pitch Key would throw the string out of tune. I had to repeatedly retune and fine tune.
Upon close examination I determined I could slide the Pitch Key much closer to the 6th string tuning peg. This widens the distance between the two strings.
Although the difference is minimal it seems to be enough to let the stabilizer do it's job.
Interestingly, while this is a problem that will affect all Martin style headstocks, it is NOT a issue with the Seagull tapered headstocks. As you can see in image below, when looking between 6th and 5th tuning peg, the space between 4th and 5th strings is more than adequate to provide proper stabilization.
