The MXL CR89 is a large-diaphragm cardioid condenser microphone with a fixed polar pattern and FET electronics. This top-quality mic is fantastic for acoustic guitars, other string instruments, pianos, and even ambient room sound due to its warm character, super low proximity effect, and impressively low noise floor; it's ideal particularly for close recording due to these desirable characteristics. And with a wide frequency response range from 20 Hz to 20kHz, as well as up to 138 dB SPL, the CR89 can pick up and recreate pretty much any sound you could throw at it with astounding accuracy.
