CELESTION

BLUE

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.
