This is a used matched pair of Coles 4038 ribbon microphones.
A true recording studio staple and an absolute classic mic, the 4038 Studio Ribbon Microphone is of British Broadcasting design (BBC) and used for broadcasting and recording such sounds where a clear smooth wide range frequency response, absent of transient distortion and relatively high sensitivity is essential.
This matched pair of 4038s is in excellent condition and comes with the cases and stand adapters.
