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 440 is a faithful
recreation of the vintage 440, the addition of the up/down toggle
gives it a modern sonic twist.
