Celestion G12M Greenback Speaker (16 Ohms)

Celestion’s first guitar loudspeaker featuring a ceramic magnet structure, the G12M ‘Greenback’ presented almost as much magnetic flux to the voice coil as an Alnico formulation, but in a much more compact space.

As a result, the Greenback became the guitar loudspeaker that paved the way for use with higher-power amplifiers. And, of course, the ceramic magnet presented its own unique tonal characteristics. The Greenback has a loud and assertive character that sounds great through a valve amp pushed into overdrive.

The speaker has evolved over the decades and still presents that instantly familiar woody tone, delivered with a knockout punch.
