Based upon the popular MA-201fet designed by David Royer, the MA-301fet adds a 3-posistion pickup pattern selector, a15dB pad and a switchable bass roll-off.

Utilizing a 3-micron gold-sputtered capsule, high-quality Jensen audio transformer, military-grade FET and custom designed low-noise resistors, the MA-301fet performs at a level reminiscent of some of the best loved classic condenser microphones. Each MA-301fet microphone is carefully tested and evaluated, then packaged in its protective case with a professional grade shockmount.
