Our Friend Helges sent us this cool link featuring Don Airey Keyboard Setup:
Gear Run: Don Airey / Deep Purple
Check out the keyboard rig of Deep Purple keyboardist, Don Airey. Obviously, he uses a Hammond organ, but he also has a lot of synths on-stage. In particular, he cherishes his Moog synth, and he treats it with a couple of TC Electronic effects: a Nova Delay to create a full and rich sound and a Nova Modulator for high quality flanger effects. On the Hammond he uses a Nova Reverb for creating a classic Hammond Spring effect.
Don has kindly provided a diagram of his setup:Download Setup Diagram
