From the Archive: Alnico Blue

T0530, the speaker that came to be known as the Alnico Blue, was the world’s first dedicated guitar speaker. It evolved from the “G12” radio speaker that was toughened to withstand the more rigorous demands of guitar amplifiers. Soon after it got a coat of Blue paint, and a legend was born….

Although produced in a number of different incarnations throughout the 60s, Alnico speakers went out of production by the 1970s due to the prohibitively high cost of the rare earth elements required to manufacture the magnets.

The in the 1990s, after the discovery of a cache of practically unused original 60s Blues, Celestion’s engineers got the opportunity to probe the speaker’s “tonal secrets”. And with the magnet materials more affordable once again, in 1994 the Alnico Blue was re-created in all its glory.
