“Dumble would refuse to build them for a lot of people, but for whatever reason, he agreed to make four for me”: Pearl Jam used Dumble amps on new album Dark Matter, reveals producer Andrew Watt

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.”
