Empress Tremolo2 Tremelo 2 Guitar Pedal w/ 4 Cables Bundle Includes 4 Cables! Tap Tempo - The Empress Tap Tremolo2 Pedal averages your last four taps so it plays in sync with your music. You can also choose different tap to tremolo rate ratios. 1:1, 3:4, 1:2, 1:3 and 1:4 are available. Rhythms - Another exclusive feature. The Empress Trem will definitely do your run-of-the-mill tremolo sound to a tee. But you can also set it to play different rhythms. Check out the soundclips for examples. Gain - A problem with most tremolos on the market is that when they're engaged, you hear a noticeable drop in volume. The Empress Trem solves this by having a gain stage on the output. It's able to deliver up to 12dB of gain without adding any distortion to the signal. Presets - Save all your settings in up to 8 presets and recall with the touch of a button.
