Celestion G12M Greenback 12-Inch 25W Guitar Speaker 8Ω
The G12M Greenback has evolved over the decades but still retains its essential sought- after tone. Angus Young has been a Greenback devotee since the early days of AC/DC.
This model 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 guitar speaker to bring drive and definition to modern high gain amps.
