Celestion Heritage Series G12-65 15ohm Guitar Amplifier Speaker


Originally created in the late 70s using more modern materials and techniques for a higher power handling the G12-65 is widely regarded as one of the best guitar speakers ever produced for use in a 4×12 cabinet. With its fast attack and tightly controlled low end the G12-65 had become a firm favourite with hard rock players by the early 80s. The precisely tuned mid-range and crisp defined top-end contribute to an aggressive crunch sound that punches through the mix while the mid-range warmth and detail give weight and depth to single notes.
