Letโs start with the hair, not because itโs anything to laugh at, but just because itโs hard to miss. Half of Karl Ekdahlโs head is shaved, while the other half of his silvery blond hair hangs past his shoulders and is swept to the left side of his face.
When you run your own business building synthesizers for the likes of musicians such as Dan Deacon, the proprieties of high-and-tight haircuts need not apply.

Then thereโs the space, chaotically ordered โ boxes stacked on a wooden set of shelves, sawdust sprinkled on the floor around the base of a CNC router โ save for the workbench at which Ekdahl spends 10, or 12, or sometimes 14 hours at a time paying meticulous attention to a hand-drawn blueprint.
From a third-floor, walk-up workshop in West Baltimore, Ekdahl spends his days staring at blueprints while assembling a line of synthesizers he has spent several years designing. Thereโs the Moisturizer, which he has been making for four years, and the Polygamist, which took him three years working part-time and $5,000 just to finish the prototype. Basically a box about two feet in length, the Polygamist features 48 knobs, several switches and colored input boxes for hooking up the synthesizer to speakers.
โOnce itโs nailed, you can build one of these fairly quickly,โ he said on an afternoon in mid-December, picking up and pointing out individual elements of his Polygamist box while puffing an e-cigarette. โBut sourcing all the parts, finding someone who can send you the parts.โ His voice trails off. Thatโs the stuff that takes the most work. Ekdahl is now starting another run of Polygamist orders, and itโll be another month or so until he has enough of the requisite parts to complete each synthesizer. Once the parts have arrived, it takes two days to build one machine.

But Ekdahl couldnโt have predicted he would be a man in his early thirties slinging down cups of coffee to fuel 14-hour days soldering wires to the circuit boards that power his synthesizers. Originally from Sweden, he moved to Baltimore seven years ago โon a whim,โ he said.
In his early days in Charm City he was living in Hampden and working at The True Vine record shop, repairing instruments and โdoing a little bit of circuit bending.โ A friend approached him with an idea for a custom synth, and Ekdahl built one from scratch โ that was the first version of his Moisturizer, which he released for sale officially in summer 2009.

โI thought I would sell 5. Iโve now sold about 700 of those,โ Ekdahl said. โI had absolutely no education with electronics at all. I learned everything online.โ
It was a rogue form of Montessori schooling. Ekdahl never attended to college, โbasically failed high school,โ and served as a computer programmer for the Swedish government for several years. But his knowledge of electronics came wholly from a mailing list run out of the Netherlands, SynthDIY, that he joined in 1996.
โEssentially, a bunch of old dudes on a mailing list. Lots of people who are on this mail list have been there as long as I have or even longer. Some of them worked with Moog,โ said Ekdahl. Prescient training, since the Moog company was the outfit of Dr. Robert Moog, a pioneering manufacturer of analog synthesizers. When Ekdahl was 18, he built his first analog synthesizer, and never looked back.
And under the company nameย Knas,ย business in Baltimoreย has flourished. In addition to electro-artist Dan Deacon, the electronic band Matmos and other musicians at Baltimoreโs annual High Zero Festival use Ekdahlโs synthesizers, which are shipped internationally and sold from three retail stores in the U.S. in addition to stores in Germany, France, Australia and Ekdahlโs native Sweden.
โBaltimore has, hands down, the best music and arts scene I have ever experienced,โ he said. Although he arrived on impulse, that scene is the reason Ekdahl stuck around. โIโve never experienced a city with so much creativity and so many creative people helping each other and getting together. My company would not exist at all without that scene.โ

Depending on what a musician needs, Ekdahlโs synthesizers are fairly competitively priced. The Moisturizer runs for $400, but Ekdahlโs Polygamist costs $1,450, and he needs $700 up front to buy the parts to complete each order. (Although Ekdahl has a tiered pricing system for musicians on a limited budget.)

All the work is done in his studio on North Paca Street, several blocks from Lexington Market. Sometimes a friend or his girlfriend helps out, but itโs mainly Ekdahl toiling away at his workbench.
โMany companies hand out circuit boards and stuff to companies in China, but we make everything ourselves as far as we can,โ said the 33-year-old. โThis is my art. This isnโt just a business. So I can outsource things and I wonโt really know how itโs made, or I can just give the money to one of my friends and have them build everything.โ
It makes sense, then, that Ekdahl feels an exceptional kinship to a place more than 3,000 miles from home. In a way, the time he has invested in his art form is equal to the time that Baltimore has invested in him.
โThe last couple of years Iโve pretty easily been able to sustain myself on this. Iโm definitely not a rich guy,โ he said. โBut I survive. I survive on doing what I love. And nobody tells me what to do. So thatโs kind of all I have.โ
