I'm only about 8 and 1/2 years late in seeing this question but I'll answer anyway! That session was recorded at Sound Castle in Silverlake by Joe Chiccarelli through a Neve 8128 console and slammed through an 1176, The bass is an early 70's Precision with maple neck with an added Jazz bass pickup by the bridge - I believe I'd retrofitted some Bartolinis in there by then - and I played very loudly through an SVT with the 8x10 cab. There was an RE20 on the cab. The P bass was strung with medium scale LaBella rounds and I played with a pick! How I remember all this I have no idea.
"If a particular bass helps you play 2% better, than use that one." - Neal Stubenhaus, 1977
