DOD ENVELOPE FILTER 440 classical rich low bottom end whichFREE SHIPPING! ENVELOPE FILTER 440 The 440 has all of the quack, squee, squonk, chicka, mwomp, and weeeooow, that you could ask for. 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.
