This 2014 update to the classic DOD 440 adds vowel-like sounds to your guitar sound, making it sing and cry with slow-filter sweeps that react to your pick attack. An all new UP/DOWN switch lets you choose which part of the sweep you want to emphasize. Guitarists will love the “UP” setting for classic envelope quack, while bassists will go for the sub thunder of the “DOWN” setting. True bypass means your signal remains unaffected when the 440 is off, and the modern 9V DC power supply input make the pedal more pedal board friendly.
