JJ Electronics 12AX7S Mid Gain Preamp Tube Metal Slides to overall lengthThe JJ Electronic ECC83MG 12AX7MG is a new take on the classic 12AX7 preamp tube. While it uses the same rugged build and thick glass as other JJ preamp tubes, this tube differs in construction from the typical 12AX7 in that it features a medium long plate. The JJ 12AXMG has a dynamic and open sound with a rich forward sounding mid range. This tube offers low noise and low microphonics.
