Every ARP is built and tested by hand on the bench in South Wales

Built in South Wales

Proudly made in Wales

Every Midicake ARP is assembled, programmed and tested by hand in our workshop in South Wales. No anonymous production line — the people who designed ARP are the people who build it, and the people who answer your email afterwards.

It is a small operation, and that is the point. It is why the free firmware updates have kept arriving years after launch, and why we still know every unit we have shipped.
