Clavia's updated Electro range prove that if you need top-quality staple keyboard sounds, playability and simplicity, Nords still lead.
When Clavia introduced the Nord C2D, they upgraded its Hammond organ model and improved its rotary speaker effect.

Happily, all of these improvements have been incorporated into the Electro 4 series
