Don Airey, legendary keyboardist for Deep Purple since 2002 and former member of Rainbow and Ozzy Osbourne, is renowned for his powerful Hammond organ sound. And yes – a keyboard player on the Hughes & Kettner website might sound unusual, but Airey’s secret weapon is a Hughes & Kettner PureTone amp, which he uses to drive his Hammond A-100 through Leslie 122 speakers. This setup delivers the rich, “old school Machine Head” tone he’s famous for, proving that great amps aren’t just for guitarists.
