Hello Spalding
Yes he does now work as a freelance demonstrator for the Korg PA1X, however it is his own and not loaned to him by Korg.
His main instrument is still the Wersi, of which various models he has played since the 80s.
The Korg is featured on his latest CD, and compliments his Wersi, giving a smooth integrated sound.
Enjoy whatever you play

Bill
