About JMK

JMK Music Pedals is based in Alexandria, Virginia, USA. We design and hand-build high-quality MIDI and sync gear for both studio and stage applications.

I’m Joe King - owner, designer and fabricator. My background spans decades of programming and music performance. In the early 1990s I began working extensively with MIDI hardware and software, and over the years of recording and performing, I came to realize there was a need for a dedicated master-clock device that could also serve as an audio metronome. That idea led to our first two products, CLOCKstep and CLOCKstep:MULTI.

Every unit is built in this workshop: from folding and drilling the enclosure to finishing, soldering, testing and final packaging.

With the exception of the printed circuit boards, each step is handled in-house. This approach gives me direct control over build quality, reliability and support.

Fabrication of a MIDI Splitter enclosure. Every metal part is formed, finished, and assembled by hand in our Alexandria workshop.

I invite you to explore the instruments, the thinking behind them and how they serve musicians, engineers and producers.

Thank you for taking an interest in JMK Music Pedals.
