Prog-metal architect Aaron Marshall shows off a pair of dazzling Mayones prototypes before he explains using a small digital footprint for tons of tones.

After the dissolution of his previous band, Speak of the Devil, Aaron Marshall forged out on his own and created Intervals in 2011. (Through the band’s existence, Marshall has remained the sole constant member and is the band’s musical pilot.)

The instrumental band is like a robust jambalaya. It uses ingredients from prog, metal, djent, jazz, and even top-40 pop to make its own cosmic stew. After two instrumental EPs—The Space Between (2011) In Time (2012)—he recruited vocalist Mike Semesky and released their 2014 full-length debut, A Voice Within. Aaron Marshall decided the best version of Intervals was that eschewing vocals and moved on to release two more LPs in 2015 (The Shape of Colour) and 2017 (The Way Forward). Each release has seen Marshall (and the culminating tours with various bandmates) push further through the prog glass-ceiling with a no-holds-barred approach redefining themselves, and the resulting genre.

During the band’s run opening for co-headliners Chon and Between the Buried and Me at Nashville’s Marathon Music Works, Intervals ringleader Aaron Marshall spoke with PG’s Perry Bean. The Canadian details his new custom builds from Mayones, talks about the power and freedom the Axe-Fx III gives his band, and even explains how NYSYNC, TLC, and Destiny’s Child still influence him today.

The emotional wallop of the acoustic guitar sometimes flies under the radar. Even if you mostly play electric, here are some things to consider about unplugging.

I have a love-hate relationship with acoustic guitars. My infatuation with the 6-string really blasted off with the Ventures. That’s the sound I wanted, and the way to get it was powered by electricity. Before I’d even held a guitar, I knew I wanted a Mosrite, which I was sure was made of fiberglass like the surfboards the Beach Boys, Surfaris, and the Challengers rode in their off time. Bristling with space-age switchgear and chrome-plated hardware, those solidbody hotrod guitars were the fighter jets of my musical dreams. I didn’t even know what those old-timey round-hole guitars were called. As the singing cowboys Roy Rogers and Gene Autrey strummed off into the sunset, the pace of technology pushed the look and sound of the electric guitar (and bass) into the limelight and into my heart. Imagine my disappointment when I had to begin my guitar tutelage on a rented Gibson “student” acoustic. At least it sort of looked like the ones the Beatles occasionally played. Even so, I couldn’t wait to trade it in.
