This used Empress Nebulus modulation pedal offers a powerful trio of effects—chorus, flanger, and vibrato—all housed in a space-saving enclosure. Each effect includes three unique variations, giving players access to nine total voicings, which can be stored across eight user-configurable presets for quick recall during live or studio use. The chorus section includes options such as a rich analog-style chorus, a dynamic multi-voice mode, and a tremolo-infused chorus texture. Flanger effects include a smooth tape-style flange, a retro-inspired negative feedback variation, and a dramatic thru-zero flange. The vibrato modes cover traditional pitch modulation, a vintage Uni-Vibe-style effect, and a rotary speaker emulation. Every effect type also includes a dedicated switch to unlock extended parameters, like integrated compression in vibrato mode and a selectable tone control for warm, clean, or bright tonal shaping.

Overall, the pedal is in very good condition, shows moderate signs of wear. There is some residue on the bottom of the pedal from Velcro being applied prior. All knobs and switches are in working order.
