G12M
Way back in the 1960s, Celestion released
a version of the popular G12 guitar
loudspeaker called the G12M. These days
nicknamed the Greenback, with its medium
weight magnet this speaker had a tone that
was silky smooth and warm, while still
retaining the brightness and punch
necessary to cut through the rest of the
band. The Greenback was also a highly
articulate speaker, perfect for the
pioneering lead guitarists of the time.
A classic had been born.

Over subsequent years, the Greenback has
evolved and remains popular with guitarists
and amp manufacturers to this day. As the
speaker developed, though, its tonal
characteristics moved away from those of
the original ’60s model.

Adhering precisely to the design notes and
specifications for the original speaker, re-
discovered during our recent factory move,
and using exactly the same materials and
construction techniques, Celestion has
recreated the classic 1960s G12M for a new
generation of rock and blues guitarists.
