Four knobs cover the basics: Time, Repeats, Mix Level and Mod. Mod adds continuous variation of the delay time, giving tape-like movement or more obvious pitch wobble. A three-way toggle selects Bright, Mellow or Dark voicing for the repeats.

Internal DIP switches select true bypass, buffered bypass or a kill-dry mode for parallel effect loops. Switching uses Vahlbruch's MagTraB system, which relies on a magnet and a relay rather than a mechanical switch contact.

Each pedal is built by hand in Germany. The compact enclosure suits crowded boards, and the controls favour quick setting over deep menus.
