Inspired by the Shepard Tone illusion, this is a pedal effect you won’t find anywhere else.

Spira uses a bank of resonant bandpass filters to create the illusion of a never-ending, layered, overlapping glissando. Spira sounds as if it is continually and infinitely sweeping either up or down, creating musical tension and energy. Its texture and sweeping motion are perfect for psychedelic, drone, and ambient styles, and anywhere else you want to add movement to your sound.
