A Sunn Beta Lead-style solid-state amp would get closer.

Why it sounds like that

On Lateralus, Adam Jones played Gibson silverburst Les Paul Customs and dedicated one to the tuned-down songs. For the recording he swapped a Mesa/Boogie Dual Rectifier for a Sunn Beta Lead. He ran three amps at once, one solid-state, one non-master-volume, and one that filled the low end with a cardboard crunch. His favorite amp was a Diezel. An Ibanez delay and flanger, a Boss EQ pedal and a Dunlop wah completed the chain.
- Route one pass through different amps, or double the same notes on two passes, to make a part more powerful.
- Use the wah for transitions and flavor, not in an obvious way.
