The Empress Tremolo 2, following up the original Empress Tremolo, brings your signal through an analog path so as not to sacrifice tone but produces a digital tremolo effect using opto technology. The Tremolo 2 gives you three separate waveforms to choose from when building your trem that can be set to different rhythms for a ton of different combinations, and its added gain stage can bring up to 12dB of undistorted gain. Once you've found a trem you love, save it in one of the 8 recallable presets the Trem 2 offers.
