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.
