Hank Williams III

Used for the guitar on Straight to Hell, as stated in this May 1, 2006 Mix Online interview.

The room where the vocals, guitars and bass were recorded for disc one was a relatively large one, with 15-foot ceilings. While there was no official baffling, Hank III reports that they recorded the vocals and acoustic guitars tucked in a corner. In keeping with the minimalist approach, few microphones were used during those tracking dates and just three kinds: Shure SM7, SM57 and KSM32. Hank III sang into the SM7, used the 57 on his acoustic guitar and kept a KSM32 going at all times to capture room vocal and guitar tracks that were later blended in.

Getting tones from the stand-up bass was a bit of an issue, Hank III says, because there was no controlling the room ambience. That was solved, in part, with Hank III twisting a knob on the D1600, checking the sound as it played on his home stereo system, which includes a Paradigm subwoofer, and then returning to finish the track. “We were trying to keep some of the click of the stand-up bass and trying for it to not sound too scary on the woofy end,” he says. A 57 was placed just above the bridge of the bass, one just below, and then one KSM32 slightly off to one side and another down a hall about 15 feet.

Any other type of instrument — dobro, fiddle, pedal steel — was miked with a 57 and run straight into the D1600. Indeed, other than the mic pre’s that are present in the D1600, no other outboard gear was used on the project.

(...) The album is light on effects. “All of the reverb that you hear on the vocals is natural,” Lightman reports. “There is not a drop of digital reverb. There are delays that are very obviously delays, but all that room ambience is the KSM32 that was across the room. That was very carefully blended in. There were three or four tracks on every vocal take, which had to be treated as one take. We locked the tracks together, and all the edits were done together.”

Whereas the vast majority of today’s country music artists demand pristine and polished audio tracks, Hank III aims for vibe and personality. Rather than head to one of Music Row’s best-known studios, he and musical compatriots Joe Buck and Andy Gibson took up residence in an east Nashville home with a Korg D1600 digital recording workstation and got to work.

“It’s just three guys that don’t have any degree in recording or understand how it works doing their best,” Hank III reports. “We were all just doing what we thought halfway sounded good.” The trio showed up at the house every day for a month, working into the wee hours; as one person was playing the other would run the D1600.

Hank III raves about the now-discontinued Korg product that he uses to write and record: “When I was on the road [playing bass] with Superjoint Ritual, it would be like wake up, go into whatever room we’ve got, plug it in and start ripping out,” he says. “I’m a true believer that every independent band or do-it-yourselfer should have a machine like this.” The mobile workstation boasts an uncompressed 24-bit, 44.1kHz range with 24 channels and an 8-bus, 16-fader mixing surface.

(...) One of the vocal tracks that Lightman and Hank III turned to was a distorted vocal that was recorded into the D1600 dry and then dumped to Pro Tools. “Then I would run a stereo signal out of Pro Tools back into his Korg and he would set up a distortion patch on his Korg,” Lightman says. “We recorded the distortion part of it back into Pro Tools and mixed the distortion stereo track in with the dry vocals. That way, we were able to get a good blend of distorted and clean vocals.”

Hank Williams III used the Ampeg SVT-4PRO 1200-Watt bass amplifier head during his time with Superjoint Ritual, as evidenced by the image on Imgur.

in the video it's a rundown of everything that he uses live, I'm not sure if he uses any of the stuff for studios probably though.
