MXL Microphones Genesis
Large Diaphragm Tube Microphone


MXL Genesis Studio Tube Condenser Microphone

MXL's Genesis is a masterfully engineered tube microphone that provides clean highs, warm mids, and tight bottom-end, features attributed in part to the Mullard 12AT7 tube.  Mullard vacuum tubes are famous for producing a smooth rich tone and silky high end.

The Mullard tube used in the Genesis is sourced directly from the UK and is marked CV4024.  These are "new old stock" originally made for the Royal Air Force and NOT the Russian copy often passed off as a "real" Mullard tube.  In addition, MXL burns in each Mullard tube for 48 hours prior to shipment, ensuring flawless performance from every Genesis mic.
