Speaker - Celestion, 12", G12M Greenback, 25W

In stock

The G12M Greenback has evolved over the decades but still retains its essential, sought-after tone. This 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. 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. Very similar to its heritage cousin, this one has more aggression with clean and overdrive signals.
