The Magnatone brand was first established in 1937 in Los Angeles, CA. The company is most famous for inventing and patenting the stereo pitch-shifting vibrato effect using a non-moving part. Legendary artists such as Buddy Holly, Lonnie Mack, Jeff Beck, and Robert Ward have all used Magnatone. Magnatone Amplifiers was revived by Ted Kornblum in 2007, and today the company manufactures high-end boutique tube guitar amplifiers made in the USA. Guitarists including Billy Gibbons, Slash, Neil Young, Jason Isbell, Brandi Carlile, Lukas Nelson, Charlie Sexton, and Neko Case are just a few of the artists who play Magnatone.
