Castor & Pollux is a Juno-inspired dual oscillator and you can build your very own with this DIY kit!

This kit is an intermediate level kit. There aren’t any surface-mount components, but you should feel comfortable soldering through-hole components before tackling this project. If you’d like an easier kit to get started, check out our Big Honking Button kit.

Castor & Pollux II brings a redesigned interface and moves individual waveform outputs to an included expansion. Both versions have the same features and use the same firmware.
