DOD Envelope Filter 440

The DOD 440 (2014) makes your guitar speak with vowel-like sounds, and
cry with slow-filter sweeps that react to your pick attack. The new
addition of the up and down switch lets you choose which part of the
sweep you want to emphasize. Guitarists will love the “UP” setting for
classic envelope quack. Bassists will love the “DOWN” setting for big
dub sub thunder. The 440 is back and the neighborhood will never be the
same. The DOD Envelope Filter 440 (2014) has Level and Range controls.
Level controls the sensitivity of the envelope; adjust this control to
tailor the triggering of the filter based upon your pick attack. With a
higher sensitivity, a lower signal will affect the envelope’s effect. In
other words, with a higher sensitivity you don't have to pluck as hard
to make the effect audible. Range controls the range of movement of the
envelope’s sweep. Counter-clockwise sweeps more low frequencies.
Clockwise sweeps more high frequencies. The Voice switch allows you to
choose which part of the filter sweep you want to emphasize. True bypass
allows your guitar tone to remain pristine even when the new DOD 440
(2014) is off. This is a big difference from the original which would
color your bypassed tone. The modern 9V DC power supply input make the
pedal more pedalboard friendly.
