Magneto Audio Labs VariOhm

The VariOhm is a unique device that allows the user to control the impedance relationship between a microphone and a preamp/interface. But utilizing impedance control, one can achieve a variety of tonal settings, expanding your selection of sonic textures and colors to choose from. The VariOhm will make your current microphones, preamps and interfaces sound like completely new tools.
