Rig Rundown: Dinosaur Jr.’s J Mascis and Lou Barlow 
One of rock’s loudest guitar-and-bass duos catalogs their ferocious setups.
Bassist Lou Barlow played a Gibson Grabber on Dinosaur Jr.’s first two albums, before switching to an arsenal of Rickenbackers. Years passed and he forgot how much he liked the Grabber and its sound—until the band went on the road in 2015 to celebrate the 30th anniversary of their debut, Dinosaur Jr., and Lou borrowed this Grabber because he wanted the most accurate tone to the original albums. After that tour, Lou traded a Fender bass for the Grabber and it’s been his main ride ever since. He uses Ernie Ball Regular Slinkys (.050–.105) and purple Dunlop Tortex 1.14 mm picks.
