Exclusive GT model. An exact reproduction of the acclaimed Mullard ECC83 design, which was the tube found in most high-quality musical instrument and hi-fi amplifiers of the '50s, '60s and '70s. This tube has a complex mica design using four insulators that shock-mount the cathode to enhance stability and sound quality. Excellent all-around sonic character that adds vintage clarity and feel to any modern amp - a slightly rounder, deeper and all-around warmer tone with clarity. A lower-gain 12Ax7 tube, it is a highly musical, harmonically rich and an excellent performer.
