Originally created as a higher-power handling variant of the G12M Greenback, the G12-65 is widely regarded as one of the best speakers ever produced for use in a 4x12 cabinet.
With its fast attack and tightly controlled low-end, the G12-65 became a firm favourite in the ʼ80s with hard rock players. The precisely tuned midrange 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.
