1960A 4x12 Cabinet – 1978 – Celestion G12M T1221 Blackbacks

A superb vintage Marshall 1960A angled-front 4x12 cabinet dating from 1978, loaded with a desirable set of original Celestion G12M T1221 Blackback speakers.

By 1978, Marshall’s iconic 1960 cabinets had become a staple of stages and studios worldwide, pairing perfectly with the JMP Master Volume and Super Lead amplifiers that defined the sound of the era. This example retains its original character and delivers the unmistakable tone that has made late-1970s Marshall cabinets so sought after by players and collectors alike.

The cabinet is fitted with four original Celestion G12M T1221 Blackback speakers, each rated at 25 watts with a 16-ohm impedance and featuring the desirable 1777 Kurt Mueller cones. Combined with the 75Hz bass resonance specification, these speakers produce the warm, woody midrange, smooth top end and musical compression that made the Greenback one of the most recorded guitar speakers in history.

Tone

The G12M Blackback sits in a sweet spot between the earlier Pulsonic-coned speakers and later production Greenbacks, delivering exceptional clarity, rich midrange detail and the classic compression that vintage Marshall enthusiasts love. Whether paired with a JMP, Plexi, JCM800 or modern Marshall reissue, this cabinet produces the authentic British rock tone heard on countless recordings throughout the 1970s and beyond.

Condition

The cabinet is in good original condition for its age and remains a fantastic vintage example. There are signs of use throughout, including some wear to the covering and a few small tears, all consistent with nearly fifty years of life. These cosmetic imperfections do little to detract from its appearance and serve as a reminder of its history and authenticity.

A great opportunity to acquire an original late-1970s Marshall cabinet loaded with a sought-after set of Blackback Greenbacks.
