MXR DYNA COMP
The MXR Dyna Comp is a simple and classic compressor in a small package. Simple to use with only two controls: one for output (overall volume) and one for sensitivity. The Sensitivity control effects the compression ratio. The higher up it is turned the more sustained and squashed your signal will get.
The MXR Dyna Comp features true bypass switching and can be powered with a standard 9 volt adaptor. Current draw is 3.3 mA.
