Justin Vernon

"I think the thing I’m working with the most is the OP-1. It’s a sampler-based synthesizer, and I honestly think it’s the most important instrument that’s come into my life since I first picked up a guitar when I was 12 years old. I’m not exaggerating at all. I never leave the house without it. I don’t travel with the guitar anymore. I travel with just my OP-1. It’s been a big deal living with this thing. I love making music with it. I love traveling with it. I like using it as a writing extension. It’s a really special technology, essentially what a guitar is to me."

At 3:02 in this interview, Justin talks about his inspiration from Bruce Hornsby, and says, "I got that exact Korg M1."
