The 2014 updated classic DOD 440 brings vowel - like tones to your guitar, making it emote with slow - filter sweeps that respond to your pick attack. An innovative UP/DOWN switch allows you to select the part of the sweep to highlight. Guitarists will adore the 'UP' setting for that classic envelope quack, while bassists will be drawn to the sub - thunder of the 'DOWN' setting. With true bypass, your signal stays pure when the 440 is off. The modern 9V DC power supply input makes it super - friendly for your pedal board.

Using this Digitech DOD Envelope Filter 440 Guitar Effects Pedal is a breeze. First, connect it to your pedal board using the 9V DC power supply input. Then, plug your guitar or bass into the pedal. When you start playing, the pedal will add vowel - like sounds to your instrument's sound based on your pick attack. To customize the sound, use the UP/DOWN switch. If you're a guitarist, try the 'UP' setting for a classic quacking sound. Bassists should go for the 'DOWN' setting for deep sub - thunder tones. When you don't want the effect, the true bypass feature ensures your signal remains normal. As for maintenance, keep the pedal clean and dry. Avoid exposing it to extreme temperatures or moisture. If it's not working properly, check the power supply and connections first.
