What ever happened to them, and why the switch?
I know some people complained about the strings "slipping", but that has never happened to me in 18+ years. (maybe I'm lucky) I use 10's and was wondering if they had a tendency to slip on smaller strings or what?

I love these tuners so much I would put them on all my guitars if it were not cost prohibitive for me.
I can break a string in a verse of a song and replace one by the chorus, they were/are just genius .... to me.

I know I must be in the minority about this, and many other things (HFS and rotary switching?, bolt-on necks, anyone?) but I am just curious about the how and why of this "evolution" of the Phase tuners.

At the end of my rainbow, there is a pot of gold winged tuners.

Thanks for any information.
