Thats what Amos descirbed on AH-List.

" I am not 100% up on the technology being used but I am virtually 
certain that it is an all-analog feedback loop... it's a balanced analog 
servomotor feedback loop using hundreds of discrete transistors.
The pickups do each have an electromagnetic driver per string, but 
unlike an ebow the drive is frequency-dependent as it is getting its 
signal from the string and then feeding this vibration back to the 
string, in phase for sustain and opposite phase for mute.  So there's no 
signal processing happening to the audio... it's all analog physics 
happening between the pickup and the string."

Yepp, that would be the best!
