What kind of gear(amps, guitars) would be perfect to nail the distorted, soulful tone sublime uses on Under My Voodoo and Pawn Shop off their self-titled album? Also, what kind of amp settings would be good for nailing this tone?
Arbor A410 Bass
Dinosaur 20 Watt Bass Amp
Line 6 Spider III 75 Watt
Squier Bullet

Excuse me sir, have you been thinking tonight?

Amps, I'm not sure. Guitar, anywhere from Fender HSS to some kind of Ibanez (I think Brad used a Ibanez Sabre [or something like that] at the beginning of his career). As for the general tone, I find that

-Clean-
Bass- 8.5
Mid- 4-5
Treble-10/max
Presence (if available) 3-4.

-Distorted-
Bass- 8.5
Mid- 4-5
Treble- 10/max
Presence (If available) 3-4
Gain: Anywhere from 3-5.5 (It varies with the song)

Thats what I used when i tried out a Fender Hot Rod Deluxe amp with a fender HSS, and it sounded right on.

Further more, on that specific guitar, for distorted tones, it sounds best when you put the pick up switch to the left-most position(The darkest sound), but for the clean tones, it sounds best when you put it to the right-most position (Brightest sound).

Hope this helps.
With enough money saved you will buy a new straw skirt and coconut bikini, a airplane ticket back to civilization and a large Mesa Boogie amp and a Gibson Explorer and shred the faces off with METALLICA!
