Celestion Classic Series guitar speaker. The G12K-100 makes full use of the heaviest G12 magnet to combine huge power handling with superb clarity across a wide frequency response. A massive bottom-end, rock-hard midrange and restrained top-end make this the perfect speaker to add thump and grind to modern high-gain tones. When pushed into overdrive it responds with biting highs, chunky lows and rock solid mids.
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. With fatter lows and brighter highs, it is slightly more aggressive than its Heritage cousin.
A firm favourite with lead guitarists, the Classic Lead features a tightly controlled low-end, with strong high bass / low mid punch, aggressive mid range attack and a powerful yet controlled top-end. for power chords it has the tone to make its presence felt but the subtle high-frequency roll-off makes it ideal for solos, able to project single notes on loud stages without becoming shrill.
