Amplification, effects, and strings
Jaco used the "Variamp" EQ (equalization) controls on his two Acoustic 360 amplifiers (made by the Acoustic Control Corporation of Van Nuys, California) to boost the midrange frequencies, thus accentuating the natural growling tone of his fretless passive Fender Jazz Bass and roundwound string combination. His tone was also colored by the use of a rackmount MXR digital delay unit that fed a second Acoustic amp rig.
He often used Hartke cabinets because of their characteristic aluminum speaker cones (as opposed to paper speaker cones). These gave his tone a bright, clean clarity. He typically used the delay in a chorus-like mode, providing a shimmering stereo doubling effect. He would often use the fuzz control built in on the Acoustic 361. For the bass solo "Slang" on the 8:30 album, Jaco used the MXR digital delay to layer and loop a chordal figure and then he soloed over it. Jaco used Rotosound strings.
