The classic Greenback G12M is characterised by a controlled low-end, warm mids and detailed highs. A classic 4x12 speaker for vintage crunch.

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.
