Euro maker William Mathewson Devices (WMD), which closed its doors at the end of 2022, is back.

Founder William Mathewson has announced that WMD is leaving behind its manufacturing business, and is returning as two companies: WMD and AMMT (pronounced “AMPED”).

WMD will continue to design and produce Eurorack modules. The company is set to reveal the Performance Mixer Mk2 in May of 2023, incorporating feedback from the Eurorack community.

WMD’s new sister company AMMT will be managed by Mathewson and three members of WMD’s former design team.

“There are three people who really helped make WMD into what it was at the peak design wise – Alex Anderson, Mason Malvinni, and Matt Tanner,” explains Mathewson. “And I love working with these guys. So I thought maybe we should form a company together, where they can actually own the shit they help design and benefit long term from their efforts.”

“The split gives ownership, financial interest, and responsibility to the team that was key in the development of our digital module ecosystem, while allowing us to keep innovating together, which is the most exciting part for the four of us,” he adds. “Further, moving to contracted manufacturing has reduced my stress hugely, and I’m feeling the joy of designing creative and inspirational tools again.”

AMMT will continue development on the Metron suite and the digital drum line. AMMT’s first newly designed product will be a digital Hi Hat percussion module for Eurorack, which will bring familiar workflows to the growing world of live Eurorack performance. The Metron suite will continue to be developed, manufactured, and supported through AMMT.

The split is expected to be complete by the end of 2023, with hopes that the new modules will be in production before winter.

Details are to come via the WMD and AMMT sites. For more details, see Mathewson’s interview with Perfect Circuit.
