Jason Isbell has spoken about his love for Dumble amplifiers and what makes it “a good piece of musical gear” in his opinion.

Appearing on a recent episode of the Blamo Podcast, the singer-songwriter and gear connoisseur explains how the iconic Dumble differs from the other amps he’s used.

“If you’re on stage with a 1959 Les Paul running straight into a Dumble, you think to yourself, ‘If I don’t do something cool here, I’m gonna look like a serious idiot,’” says Isbell. “The thing about the Dumble, there’s not a learning curve like I expect.”

“You know, I had heard a few of them, played through a few of them before. But really, the difference is all of the knobs work — that’s the best way I can put it and that’s how I judge a good piece of musical gear.”

“You turn the tone knobs and it sounds very different from number to number,” the guitarist explains, “and that’s what I really fall in love with because if you got a Les Paul that’ll do that you can make it sound like a lot of different things. And with that Dumble if you bump the mid range up just a little bit you’re getting a very different sound.”

That said, the price for such a ‘very different sound’ don’t come cheap, with Dumbles being some of the most coveted and expensive boutique amplifiers on the second-hand market.

In 2022, a 1995 Dumble Overdrive Special rocketed to the top of Reverb.com’s most-watched list after being posted on the site for sale, featuring an eye-watering asking price of $175,000.
