The AM30 and AM40 are both slender front-addressed mics designed for close miking of all types of acoustical instruments and guitar amplifiers.
The AM30 is a mid-sized, true condenser front addressed microphone with a Class A FET preamp designed for acoustic instruments and vocals. As an instrument mic, the AM30 offers more warmth and proximity effect than a "pencil-type" small condenser. Like the AM40, the AM30 includes a front-address removable cardioid capsule, which is interchangeable with two optional capsules.
