Alec John Such used a Kramer Forum III bass, custom painted in neon camo by George Felise in the 1980s. This is evidenced by numerous promotional images and posters, as well as his appearance with the bass in the music video for "Lay Your Hands On Me" at the 2:14 mark. The customization and use of this bass by Alec John Such is further supported by George Felise's account on Facebook, under the caption "Kramer Guitars Neptune NJ."

He plays this bass throughout this show. This bass was stickered up as you can see in the show. This bass was the second bass recorded with, we can see him with this bass as early as 1988, which is the late Pleasures of The Flesh era. He used this bass to record Fabulous Disaster and Impact is Imminent. He is seen using this bass up until his retirement from Exodus. This bass really helped change his tone up, obviously it could also be the possible amp changing, but this bass is lighter, thinner, and more metal than his p bass he had and used for the first two Exodus albums. This bass has active Spector Precision and Jazz pickups, it's neck through, and way thinner. His tone changed for the cool sounding thumby, yet aggressive sound of his p bass to this more clearer and dialed in bass tone as you can hear in the performance. The best example of this bass's tone is in the sadly short bass solo in Corruption.
