Esteemed producer Andrew Watt has revealed that the iconic amp designer and builder Alexander Dumble made four custom amps specifically for him – and Pearl Jam went on to use these amps on their newly released 12th album Dark Matter.

In a new interview with SPIN, when asked whether any specific gear wound up being used a lot, Watt explains: “A guy named Alexander Dumble made the amps. He was a very strange guy who unfortunately passed away in 2022.”
