Spira Is Available Now
/The Spira filter modulation pedal is in stock and ready to ship to you! Get it here, or at Reverb or Amazon.
Inspired by the Shepard Tone illusion, this is a pedal effect you won’t find anywhere else. Up to 24 parallel resonant filters sweep infinitely, while you have complete control over speed, slope, resonance, blend, and more.
Spira is built on our high performance FPGA platform, which allows us to fit a lot of power in a small package.
