II IGB-DLX bass from summer 1990 to late 1992 on 1992's Angel Dust. Even though he did have his SB Integra bass by 1986 he still used the Gibson for most of touring and recording from 1986 to early 1988 when the Grabber had according to Gould from a Q&A for the 30th anniversary of The Real Thing album, "was being literally held together with duct tape and the Aria was a better bass overall". In the music video for their song "Evidence", he is seen using a Fender Jazz. He began with Peavey amplifiers, he used the Peavey Mark III Bass Head on We Care a Lot, and Introduce Yourself and used the Peavey Mark IV Bass Head on The Real Thing and Angel Dust. And he has used them his entire career, mainly for the way he loved that the speakers in their amps broke up easily. He also at times used Ampeg SVT heads and cabinets too off and on at select shows, mainly during the first part of the Second Coming tour. He stated that he used a Fender Bassman 300 for the recording of 2015's Sol Invictus, saying that "it sounded like a tractor going through a supercharger". He also in the 90's used a Peavey TB Raxx rack preamp recommended to him by Lee Sklar at the 1990 MTV VMA's, and a Tech 21 Sansamp PSA-1. Starting around 2014 was endorsed by and began using Aguilar pedals, amps & cabinets, but later used Darkglass amps, cabs & effects. He is known for employing a wide variety of playing styles, alternating between using a plectrum, slapping, and fingerstyle. He also used an Ibanez Tube Screamer and a DOD Stereo Bass Flanger on The Real Thing album and the following tour for that album. Here is a list of the strings he has used over the years: Rotosound Swing Bass 66 (Early years-Early 1989) Dean Markley Blue Steels (Mid 1989) D'Addario Pro Steels/Nickel Bass Strings (Late 1989-1997) Dunlop Nickel Bass Strings (1997-Present Day).
