Rig Rundown: Dinosaur Jr.’s J Mascis and Lou Barlow [2017]

One of rock’s loudest guitar-and-bass duos catalogs their ferocious setups.

To match J’s firepower, Lou brings a trifecta of amps that includes a Peavey Centurion Mark III head into a 1x15 cab, a mid-’70s Ampeg SVT head and matching 8x10 cabinet, and a Marshall JCM 800 head with a 4x12. In a 2016 interview with PG, Lou had this to say about his setup: “I usually play an old SVT through a regular SVT cabinet. It’s really heavy and great sounding. I also play a Marshall 900 guitar head through a 4x12 cabinet. And at home, when I have my real rig, I play a transistor Peavey head through a 1x15, because that’s the original sound that we used to have. I still really like it. I like a really overdriven transistor coming through a 15. It just has a certain familiar sound. I mix the three together.”
