Re-released
ten years ago for our 70th
anniversary, the G12H evokes
the sounds of the classic
1960s and ’70s rock bands.
Loud and proud thanks to its
heavy magnet structure, the
G12H provides a fusion of
the Vintage 30 and the
Greenback characteristics,
producing a thick, warm and
syrupy sound while still
retaining a tight and
focused bottom end.
When played clean, the
speaker remains clear and
musical without ever
sounding harsh. In
overdrive, pick attack is
vividly articulated with
sustained notes trailing off
into warm harmonic tones. |

Celestion’s
first guitar loudspeaker
featuring a ceramic magnet
structure, the G12M
‘Greenback’ presented almost
as much magnetic flux to the
voice coil as an Alnico
formulation, but in a much
more compact space. As a
result the Greenback became
the guitar loudspeaker that
paved the way for use with
higher power amplifiers.
And, of course, the ceramic
magnet presented its own
unique tonal
characteristics.
The Greenback has a loud and
assertive character that
sounds great through a valve
amp pushed into overdrive.
The speaker has evolved over
the decades and still
presents that instantly
familiar woody tone,
delivered with a knockout
punch. |

The Vintage
30 resulted from Celestion’s
early steps to preserve the
tonal characteristics of
vintage speakers while using
contemporary materials and
construction techniques.
As the 1970s progressed and
guitar amplifiers became
more powerful, guitarists
began to demand the tone of
the Celestion Blue in a
speaker that could handle
more power. So in the early
’80s, Celestion made
pioneering use of Laser
Doppler Interferometry to
analyse the cone behaviour
of an original Celestion
Blue. We could then form a
precise model of our vintage
speaker characteristics and
apply it to a speaker design
using new materials for
greater power handling.
The result was an instant
classic. Seemingly twice as
loud as anything else at the
same power level, the
Vintage 30 handles massive
overdrive sounds with ease.
Tight bass, fat mids and a
smooth, harmonically rich
top end have made the
Vintage 30 an excellent 4 x
12" loudspeaker. Of course,
it’s also suitable for any
other cab! |

The world’s
first dedicated guitar
loudspeaker and a part of
musical history. Back in the
1950s, Celestion witnessed
the emergence of a new breed
of musician – the electric
guitarist – and responded to
their needs for a rugged,
reliable loudspeaker by
modifying the G12 radio
speaker. The unique tonal
character of the Celestion
Blue, combined with the
valve amps of the time,
helped to define the
electric guitar as we know
it today.
Variations of the Blue were
actually released in several
different liveries,
including chrome, red and
silver. Used by many classic
amplifier manufacturers of
the time, it was the
speaker’s adoption by Vox
for their AC30 that ensured
the Blue’s place in history.
The Blue has a bright,
lively character with a
carefully controlled bottom
end and shimmering highs
which remains popular and
distinctive to this day.
Loaded into a single 12" or
2 x 12" cabinet, this
legendary loudspeaker suits
a wide range of playing
styles. |

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. |

If the G12M
was to become a classic, it
was the G12H with its
heavier magnet that really
characterised the sound of
rock guitar for the new
breed of player that emerged
in the 1960s. Listen to any
Hendrix recording and the
chances are you’re hearing
the unmistakably creamy
tones of the G12H.
Originally available in two
versions – low resonance for
bassists and high resonance
for guitarists – both were
in fact embraced by guitar
players for their unique
tonal characteristics.
The new Celestion G12H is a
perfect recreation of the
low resonance model, right
down to the voice coil
former material, glue
formulations and vintage,
solder-only tag panel.
Suitable for use in all
cabs, it exudes thick,
syrupy tones with a deep,
growling bottom end. |
