QOTSA "Hangin' Tree" effect?

[Simto]

Hey guys

I've been looking around the internet to see if somebody knew what effect the bass has on Queens of the stone age's "Hangin' Tree"
Is it a chorus pedal? some type of octave? It's definitely got some grit, so i'm guessing some type of drive pedal too.
I'm not sure, so i was hoping one of you guys might know? or could make a wild guess to what you think they used for this song.

Here's a link to the song

Don't forget that this is a studio recording. Many things could have been added "at the board" lots o' bands do it.

As far as I know, its a P Bass through a cranked SVT.

[Gasman]

IIRC his tone comes, in part, from how he mics himself. He does overdrive a couple of SVT's, but he angles the cabs away from each other and puts the mic in the crevice between them. That, a good P bass, and some flatwounds, you're there.

Nick Oliveri's sound is pretty straightforward by most accounts. Fender P, 810s, cranked SVT.

Isolated bass track.

This is what I call the Holy Trinity. It seems to just work.

You could get pretty close with a VT bass though.

Cool, i don't know why i haven't noticed how he mics the cabs, very cool, i'll have to look into that technique.
Could it be the micing technique that gives it that chorusy effect?? or like SunBass said, some outboard gear they used? To me, it just doesn't sound like a completely dry signal.. but then again, i'm a guitarist so what do i know
I love flatwounds, i don't think i'll ever go back to rounds. They just have the sound i love.

@Road Bull: Thanks for the link, i'm checking the other tracks out too!
