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.
