The ZOIA LE by Empress Effects expands the concept of what a stomp-box can be, allowing you to craft custom effect rigs, synthesizers, sequencers or controllers from the ground up. Its grid-based interface, OLED display and extensive connectivity mean you’re not constrained by preset categories—you design the signal path, the modulation, the interactions.
It arrives with a wide set of modules, including oscillators, filters, envelope followers, delays, reverbs and more. Onboard memory lets you save and recall patches on stage or in the studio, while MIDI, expression pedal/CV and an SD card slot make it a hub for creative workflows.
Built into a sturdy chassis with real-world routing, stereo I/O, and a high-fidelity audio path (24-bit/48 kHz AD/DA, 32-bit internal) the ZOIA LE is engineered for both experimental exploration and polished performance. Whether you’re sculpting ambient textures, building modular synth rigs, or designing custom multi-effect chains, this pedal offers near-limitless possibility.
