"I’m absolutely delighted with the way these amplifiers turned out. They have a bold, punchy, and totally unconstricted sound that is like no other amp I’ve played – a sound I’ve been chasing for 30 years. I hope you enjoy them too."
~ Mark Bartel
Mark Bartel founded Tone King in 1993 and spent twenty-plus years building some of the most respected amps in the boutique world. When that chapter ended in 2016, he did something most people in his position wouldn't have: he threw out the playbook and started over.
Bartel Amplifiers is what came out of that, and every single one is built by Mark himself in his Baltimore shop, down to the turret boards and the molded knobs. The amps are simple, all tube, hand-wired, and housed in solid wood cabinets that are tuned rather than just assembled.
What he was chasing is an amp that behaves like an acoustic instrument, where every note comes back full and resonant and harmonically rich rather than glassy or harsh.
We carry Bartel because that's exactly what these do. Plug in a good guitar and the amp gets out of the way, and everything you were doing with your hands is suddenly right there in the room with you. There aren't many amps we'd say that about.
One person builds them
Mark builds each amp himself. He makes his own turret boards and molds his own knobs, which sounds like overkill until you understand that thirty years of amp design taught him exactly which details he refuses to hand off.
The cabinet is part of the circuit
Bartel amps live in finely tuned solid wood cabinets, and that's a design decision rather than a cosmetic one. The cabinet's natural acoustic behavior is built into how the amp sounds, which is a big part of why these feel more like an instrument than a box with speakers in it.
A fresh start, not a continuation
When Mark launched Bartel, he deliberately left the Tone King work behind and went back to basic research. The Sugarland, Starwood, Roseland, and Swingland aren't updated versions of anything. They're original designs from someone who'd already proven he could build a great amp and wanted to find out what he'd do with a blank page.
