Ask those who use a vintage Marshall amplifier what their favourite speaker is and they'll probably tell you its the Celestion G12M Greenback. This 12-inch speaker - with its characteristic green magnet cover - has literally set the tone for rock and roll in since sixties. Does the name Jimi Hendrix ring a bell? The Greenback G12M has a capacity of 25 watts and is characterised by full, controlled bass, warm mids, and detailed trebles. It is the perfect speaker for 4x12 vintage crunch sounds. G12M Greenback: the ultimate rock and blues speaker The Celestion G12M Greenback was used in most Marshall speaker cabinets from 1966 onwards, whether they were 1x12 combos or 4x12 stacks. The sound of the G12M with its ceramic magnet is full of mid-range crunch combined with a wonderful compression when you push the speaker to the brink. It is a different sound entirely compared to the Alnico speakers used by Marshall and Vox back in the day. The Greenback offered guitarists a fuller tone while retaining clarity, making the Celestion G12M Greenback the ultimate guitar speaker for rock and blues - and so it remains to this day! Hand-built with the finest materials and components The Celestion G12M Greenback has a loud, assertive character. It sounds great when paired with a valve amplifier that is driven to distortion. Through the years, this speaker has undergone 1731539722 several changes. However, the G12M still features the familiar warm and open sound with plenty of clarity and punch to pierce through the band mix. It's also hand-made with the best materials and components for a reliable, unrivalled sound.
