Projects > Drip Electronics 175 VariMu Compressor
The Drip 175 is an exact recreation of the Urei/Universal Audio 175b vari-MU limiter. Drip Electronics offers a PCB and support for this project. Since the 175 shares the same vari-MU compression style as the Fairchild 660/670, Drip has also developed an add-on which allows the 175 to emulate the Fairchild time constants.
