Celestion's Hempback Guitar Speaker Now Available

Celestion, the world’s premier designer and manufacturer of guitar loudspeakers, well-known as the “Voice of Rock & Roll” behind many of the world’s most memorable guitar performances, is very pleased to announced the worldwide retail availability of the highly-anticipated G12M-50 Hempback guitar speaker, which takes Celestion tone in an exciting new direction.

The first-ever hemp cone guitar speaker built by Celestion, the Hempback represents a new development in Celestion’s never-ending pursuit of outstanding tone. The cone was specifically chosen for its tonal character and combined with a medium-weight ceramic magnet, the Hempback has a tone that is distinctive and well-defined: delivering a balanced low end, plenty of mid-band character together with smooth, silky highs.

The speaker is particularly targeted for use in American voiced amps, for example combos such as a Fender® Deluxe Reverb® or Blues Jr.®, delivering true American-flavoured tone along with cleans that are second to none. Load up a Hempback for a smooth and “smoky” sound that’s musical and responsive, and let the hemp tone shine through.
