Grayscale is dedicated to improving the user experience of modular synthesis. We specialize in designing replacement front panels for existing modules and creating unique redesigns of existing open-source hardware. Our first Eurorack modules were released in 2014, followed by Buchla-format modules in 2017 (which are now available through a new brand called 1979).

Changing Front Panels

It's easy to install alternate panels. Watch the videos below for examples. Note that most aluminum panels have a protective plastic film on the front, which should be removed before installation. If your panels look scratched upon delivery, it's probably just the film.
