It works equally well on guitar, bass, and keys. Use out for funky chordal work, simulated wah, or trippy drawn out filter sweeps. While the 440 is a faithful recreation of the vintage 440, the addition of the up down toggle gives it a modern sonic twist, allowing you to control which part of the sweep is emphasized.
