Pino Palladino's writing technique?

Hello everyone,

I came across Robert Trujillo's wikipedia entry, and it says
"For recording purposes, Trujillo uses his own code for writing down bass arrangements. Inspired by an article by Pino Palladino, he developed this during the recording sessions for Jerry Cantrell's Degradation Trip which, according to Trujillo, had him working from "little hoodrat demos" with nearly inaudible bass.[10]"

I tried hard to find any more information about that technique, but unfortunately the luck was not on my side.
If anyone got further details about Robert's technique, or the mentioned article from Pino, I would really much appreciate it!


Cheers and thanks a lot!
