Nevertheless, the decision to embark on an “unplugged” U.S. acoustic tour using Bose S1 Pro speakers as monitor wedges was no joke.

(...) The decision to bring S1 Pro boxes on tour for onstage monitoring came at the urging of vocalist, multi-instrumentalist and songwriter Adam Gardner. “I have one at home,” Gardner says.

As it turns out, the band has had a relationship with Bose for some time, initially using the slimline L1 articulated arrays at house parties and side-stage pop-up surprise performances at their own shows. Gardner first experienced the S1 after securing a pair for an album release listening party on the beach at his annual On the Ocean festival in Maine.

“I loved the way it sounded,” he says. “Then I did some solo gigs with it and noticed how crazy guitar sounded through it, and how easy everything sounded. You could just plug into it and everything sounded how you wanted it to.”

Gardner brought along an S1 for a couple of recent acoustic shows. “Jim saw me using it” and suggested it might work on the upcoming acoustic tour, Gardner says.
