voila l'ensemble de son matos:
"Robert Trujillo has been playing Tobias basses for years. His arsenal includes a Tobias Classic 5-string made of bubinga, wenge, and alder; a Basic 5-string with a blue-finish flame- maple body; a custom-painted Basic 6-string called "Uno Mas"; and a fretless Basic 6-string. He also uses a Fernandes 8-string and a Music Man StingRay 5-string. All of his basses are strung with light-gauge Dean Markley Magnum roundwounds with a heavy B (.130). Trujillo's tech, Scott Uchida, installs his own preamp in all of Robert's basses, and he's also fitted the Tobias instruments with EMG pickups and rewound the pickup in the Music Man.
For live work, Robert uses a Nady wireless and feeds the signal into a T.C. Electronic chorus pedal. Next comes a dbx 160X compressor (modified by Uchida for a smoother high end), then a BBE 411 Sonic Maximizer, and finally an Uchida splitter box, which feeds up to six Ampeg SVT-III heads. Each head powers one Ampeg SVT810DL 8x10 cabinet.
In the studio, Trujillo uses a variety of Ampeg and SWR amps for clean miked-amp sounds; he gets his dirty sounds with a Peavey 5150 guitar amp. He also takes a direct line, blending it with the miked-amp tracks for the final mix."
