Ozzy Osbourne

At 5:11, Black Sabbath´s Sound Engineer Gregory R. Price says that Ozzy Osbourne is using an Shure SM58 Microphone.

In the live video "War Pigs" from 'The End,' Ozzy Osbourne is seen using the Shure UR2/BETA58A Handheld Wireless Microphone Transmitter, identifiable by its characteristic blue line. Additionally, he uses the wired version during Black Sabbath's performances in "The End" and "The End Of The End" studio sessions.

Ozzy Osbourne has incorporated the Eventide Clock Works H910 Harmonizer into his sound, a key element of his musical identity as detailed in the Red Bull Music Academy article, "How the Eventide Harmonizer Expanded the Possibilities of Sound."

Ozzy states in his autobiography that he owns an ARP 2600 Modular Synthesizer.

Ozzy states in this interview with Guitar Center that he uses Lee Oskar harmonicas.

In the Sound On Sound article "Secrets Of The Mix Engineers: Kevin Churko," it's noted that Ozzy Osbourne was already using the AKG C12 VR microphone before Kevin Churko began working with him. This highlights the microphone's role in Osbourne's recording setup.
