Sony C-38B Condenser Microphone with Case. This microphone was in use in a home studio environment. Note that this microphone shows signs of use with small chips and scrapes on the body, this unit also has an optional 9v battery compartment for use in areas where no 48v Phantom is available. The Pattern Selector and the Filter Selector both work, though the pattern selector can feel stiff when switching and the filter selector has an off position which passes no audio. Please reach out if you have any additional questions about the microphone or it's condition.
