Celestion G12M Greenback

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 general consensus is that the lower wattage Greenback is very similar in tone to the Vintage 30 except for that it has speaker cone break up SOONER than the Vintage 30, a tad more bass, and lots of great mids and highs. The Greenback has a loud and assertive character that sounds great through a valve and pushed into overdrive. The speaker has evolved over the decades and still presents that instantly familiar wood tone, delivered with a knockout punch.
