Re-released  for our 70th anniversary, the 16 ohm 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.
Celestion G12H 70th Anniversary 12" 16 Ohm Guitar Speaker
 
It's hard to escape the sound of the  G12H, just listen to  any   Hendrix  recording and chances are you'll be  hearing a whole raft  of   them powering the guitar out of the mix.
With a heavier magnet than the G12M,  this faithful recreation    captures the  unmistakable mojo of late 60s rock  guitar tones. Used    singly it exhibits a  pleasing, strong low-end, but it's in a  4x12    configuration that it generates  the great chugging 'thump' that the     guitar heroes of the day were renowned  for. With a densely complex and    buttery  mid-range and a finely detailed top-end,  the G12H is   excellent  for cranking out  huge, dark power chords, with smooth  and   rich bridge  pickup tones and flutey  neck pickup tones.
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.
