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. While its primary application is to be used with a microphone, the Tube MP is an exceptional direct box - impedance matching, amplifying and improving the sound of any instrument plugged into it. 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.
