In this diagram, it shows Adam using a Dual Rec as part of his guitar rig.

This YouTube video features DunlopTV and their interview with Adam Jones's guitar tech since 2001, Chris "Frank" Leahey who points to the Diezel (4:18s) and says, "And these Diezels which are insanely loud."

In an interview for Guitar World magazine, Adam said, "Right now, for my live setup I’m using two Diezel heads and an old vintage Marshall bass amp that’s been hot rodded. The good thing about the solid-state stuff is if you know what you like, you can go to any store and buy exactly that. But with the tube stuff, you gotta find the amp and hold onto it. I’ve never heard two Marshalls that sound the same"

In this article from Gibson.com, Ted Drozdowski writes "Live and in the studio, Jones uses a blend of amps. Two favorites are a 1976 Marshall Super Bass and a Diezel VH-4 “blueface”".

In this image of Adam Jones of Tool performing live, two Diezel VH4 100W Tube Guitar Head Amps can be seen.

This article from Gibson's website suggests that Adam Jones experimented with using a vintage Sunn "lead" head in the studio when recording Lateralus

Jones is also a glutten for effects. On the intro to “Reflection” and “The Grudge,” both from Lateralus, he employs a vintage Moog Taurus bass pedal system. But aside from the Heil Talk Box on 10,000 Days, run through a Roland JC-120 and juiced up by a dynamic compressor, Jones’ choices of effects is less esoteric. His wah-wah pedal is a dependable Cry Baby, and his stable of other sound generators includes Boss DD3 and DD5 digital delays, a BF-2 flanger, a Line 6 Delay modeler (which also samples on the fly), a Strobostomp tuner, a tremolo pedal, chorus, and an array of distortion boxes. During experimental phases, Jones has taken the stage with multiple pedal boards at his feet. The irony of this rundown is that Jones has gone on record saying he doesn’t like to use pedals.

This YouTube video from DunlopTV interviews the guitar tech of none other than TOOL's, Adam Jones. Guitar tech since 2001, Chris "Frank" Leahey guides the interviewer passed the amps and cabinet.

At 4:19 of this video, the interviewer says, "This looks like a bass cabinet!"

Frank states that is IS in fact a Mesa Boogie 2x15 Bass Cabinet. He does not mention the model, but due to the cloth covered over the speakers and the appearance of the side handles, we can conclude that this is the Vintage PowerHouse model.

In this video Chris Leahey shows the amp in which Adam uses for the Talk-Box, at 1:25

Live and in the studio, Jones uses a blend of amps. Two favorites are a 1976 Marshall Super Bass and a Diezel VH-4 “blueface.” On the latter, he never switches out of the ultra-high-output third channel. During the recording of 2001’s Lateralus, he reportedly experimented with a vintage Sunn lead head, too, and for 2006’s 10,000 Days he blended his Super Bass and Diezel with a Bogner Uberschall and a Riveria Knucklehead. Jones drives all his amps hard to achieve his responsive tone. He also uses Mesa Boogie Dual Rectifiers and Marshall and Mesa cabs

This cab can been seen in multiple photos of live performances with Tool.

Three Fillmore 50’s are seen on stage throughout the performance of Invincible. Easily recognizable at 1:20.

In an Instagram story from Adam Jones' account, he showcases a Mesa/Boogie Mark VII Tube Amp Head. The video begins with a close-up of the amp head and then zooms out to reveal the head is sitting on a Recto 4x12 straight cab with a custom grey grille cloth on a podium, before panning towards an empty venue. The accompanying text indicates that he is conducting a soundcheck for a gig, suggesting the amp's use in his live setup.
