Celestion G12M Greenback 25W Speaker - UK 2023

Here is a Celestion G12M Greenback 25W guitar speaker, 16-ohm, offered in as-new condition and still housed in its original box. This speaker is a faithful recreation of the classic 1960s Greenback design, one of the most iconic and widely used guitar speakers in British rock history.

The G12M Greenback is renowned for its warm, woody tonal character, featuring a smooth midrange focus and naturally compressed response when driven. It produces a rich, harmonically complex sound that has become closely associated with vintage rock, blues, and early hard rock recordings.

With its 25-watt power handling, this speaker is ideally suited to lower- and mid-powered valve amplifiers, where it can be driven into its natural breakup zone to deliver expressive, touch-sensitive dynamics. The result is a responsive and musical feel that reacts strongly to playing style and volume changes.

Tonally, the Greenback is known for its slightly rolled-off top end, pronounced midrange presence, and organic low-end response, making it an excellent choice for vintage-style combos and cabinets where character and musicality are prioritised over high-headroom clarity.
