The Tube MP is the world's most popular external tube microphone preamp. Whether you're working with a digital, computer or analog recording system, the Tube MP's TEC award nominated design will allow you to obtain professional recording studio results at a fraction of the cost of comparable equipment. The hybrid design of the Tube MP allows it to add warmth and fatness to a signal while maintaining exceptionally low-noise and high quality.

The usage of external mic/line preamps has become increasingly popular over the past several years. The Tube MP offers superior performance and sound quality to the “on-board" preamps found in today's low-cost mixers and multi-trackers. It's sound has been consistently favored over other products costing upwards to ten-times its price. Professional quality sound combined with professional features like a hand-selected 12AX7A tube, phantom power and phase reverse are what have made the Tube MP a staple in thousands of studios worldwide.
