Building on the platform of the Blue, the Gold is a higher-powered, Alnico-magnet speaker that recreates the unmistakable sonic signature of a ʽwell played-inʼ original. Over time, the high frequencies of a Blue soften and become less chalky as the cone becomes more flexible – a much sought after characteristic that the Gold exhibits straight out of the box. Also present in the Gold sound from the outset is an added warmth and complexity in the midrange which, coupled with the classic Alnico qualities of a laid-back attack, rounded low end and brilliant belllike highs, deliver huge rhythm voicings and saturated vocal lead tones.
The Gold is a wonderfully expressive and revealing loudspeaker, affording guitarists an unprecedented degree of dynamic control. It has already become a favourite for many working players worldwide whether picking and bending with Brad Paisley, or rocking hard with Danny Spitz of Anthrax.

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.
