Empress Effects Tap Tremolo Pedal Pristine Sound - The Empress Tap Tremolo2 Pedal has to be heard to be believed. It's whisper quiet and free from the "LFO throb" usually associated with tremolos. We dare anyone to find a better sounding tremolo. Gain - The Empress Trem has 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. True Bypass - The Empress Trem employs true bypass, so you can be sure that it's not affecting the signal when disengaged. Buffered bypass is also available if that's your thing. Perfect Size - The enclosure measures approximately 4.5" by 3.5" by 1.5", which is delightfully small when considering all the features packed into this unit.
