A Cult Heirloom, Reissued as the Anniversary
Born from the Celestion tradition that shaped the sound of British rock, the G12H established itself thanks to its heavy magnet and authoritative tone. The Anniversary version celebrates this heritage by reissuing the sonic character of the historic model, prized by those seeking the texture and dynamics of 60s and 70s recordings. It features the combination of tight lows, solid mids, and bright highs that instantly fit into a mix.
For Which Guitarist and Uses?
The G12H Anniversary is aimed at rock, hard rock, blues-rock guitarists, and fans of punchy British tones. It suits tube amps with a gritty character as well as cleaner circuits that require projection. In a 1x12 cabinet, it provides body and definition; in 2x12 or 4x12 setups, it delivers a spectacular foundation, equally effective for rhythm parts and singing leads.
What Makes It Stand Out
Its H ceramic magnet delivers a fast response and precise attack, ideal for tight palm-muting as well as open chords rich in harmonics. Its 100 dB sensitivity helps the amp breathe and remain clear at rehearsal or stage volumes. The frequency response centered on the essential guitar range favors a meaty midrange without harshness, while the highs stay clear and articulate.
