The  G12-50GL, named after George Lynch, was created to provide a  harder-edged and more modern sound while also keeping the complexity  found in 60's vintage models.
Celestion G12-50GL Lynchback 12" 8 Ohm Guitar Speaker 50W
One of the most recognizable names in the world of heavy metal  guitar, George Lynch has recorded more than twenty albums, and is famous  for his accomplished and inventive guitar playing. In 2010, George  challenged Celestion to build his dream guitar loudspeaker. He wanted a  new style of speaker, blending world-renowned Celestion vintage tonality  with the capability of providing, on demand, a harder-edged and more  modern sound.
Tonally, the G12-50GL Lynchback incorporates the  kind of detail and harmonic complexity found in vintage models of the  late 1960s, combined with increased headroom, and the attitude,  aggression and mid-band character of some of the more modern Celestion  speakers. The result is an ideal balance between a detailed vintage  warmth that makes your lead sound sing, and an up-front attitude that  delivers punchier rhythm tones capable of cutting through the mix.
