David Cook

It says that he uses a prophet 6

I’ve been using Nord products for over 10 years now. From jazz clubs to stadiums, performing arts centers to arenas, TV shows, recording studios or hotel rooms, these are among the most versatile and best-sounding boards in the world. The attention to detail that Nord puts into both the sound and layout of their products means that you can sound like a pro right out of the box, or dig a little deeper and constantly be rewarded. You can tell these keyboards were built by people that love to play music.

In an Instagram post, David Cook is seen with a Korg Kronos 2 61 synthesizer.
