The G12M Greenback 8 ohm version exhibits all the classic G12M characteristics but is voiced with additional broad mid-range attack and restrained top-end to give a forward, punchy attitude to chords and a searing lead tone without fizz.
Celestion G12M Greenback 12" 8 or 16 Ohm Guitar Speaker 25W
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. With its well-controlled low-end it can be used singly in low-powered amps, or in multiples for high-power rock heads. It’s an ideal speaker to bring drive and definition to modern high gain amps.
