Description: This is a simple microphone preamplifier circuit for a wide range of microphone types, with good pre-amplification to attach to your larger stereo amplifier. This circuit is suitable for use with normal stereo amplifier line/CD/aux/tape inputs. The microphone preamplifier works great with guitar pickups, piezo disks, and can take both dynamic and electret microphone inputs (preamplifier provides power for electret microphone elements). This is a simple, easy to build circuit that is flexible and very handy when working with microphones and amplifiers.

Board does not come assembled. You will need to purchase the components separately.
