A high-end tremolo pedal from Canadian manufacturer Empress Effects that combines high sound quality and functionality at an ultra-high level. By digitally controlling high-quality analog circuits, it combines excellent analog sound quality with expanded functionality. The ratio setting allows you to adjust the tremolo speed and rhythm pattern, with tap tempo input for a deeper approach to tempo. Three waveforms—tube, square, and triangle—allow for flexible sound creation. The tube mode, modeled after a '65 Fender Vibrolux (brown), offers particularly impressive sound quality. You can set up to eight presets (any number between 1 and 8 can be set), so you can switch between multiple presets with different tremolo speeds and types within a song. It also comes equipped with a control port that supports CV/MIDI and expression pedals.You can use an expression pedal to control the settings of multiple knobs simultaneously, enabling expressive performances and changes in volume and speed that were previously impossible with conventional tremolos. The waveforms are tube, square, and triangle, and there's an advanced mode that allows for output gain adjustment, tremolo speed adjustment, and various other settings, making this the ultimate high-end tremolo that has everything professionals want. The tremolo speed can be synchronized with the tremolo mode, and two different speeds can be combined in two-speed mode.
