Description
Bassists have always had to fight envelope filters built for guitar players. The reissued DOD 440 fixes that with a dedicated Up/Down switch, so instead of chasing a quacky wah tone that was never meant for your range, you can flip Down and let the filter dig into the low frequencies where your bass actually lives. Think sub-heavy dub thunder, not thin treble squawk.
- Level sets how hard you need to dig in to trigger the sweep — crank it for a hair-trigger response, back it off if you want the filter to stay quiet until you really lean into a note.
- Range shapes where the sweep sits across the frequency spectrum: counter-clockwise keeps things low and woofy, clockwise pushes the sweep up into brighter territory.
- True bypass means your dry tone stays untouched when the pedal’s off — a real upgrade over the original 440, which colored your signal even bypassed.
Built into a lighter aluminum chassis with a standard 9V DC jack, this one’s ready for the pedalboard, not just the practice room. A blue status LED keeps things visible on a dark stage, and the all-metal construction means it can take the abuse of a working gig schedule.
- Envelope filter with dynamic, pick-attack-driven sweep
- New Up/Down switch to emphasize the range that suits bass or guitar
- True bypass circuit
- 9V DC power jack (also runs on a 9V battery)
- Blue status LED, lightweight aluminum chassis
- 1/4″ instrument in/out, 1M Ohm input impedance
This bundle includes two free 6″ patch cables, so you can get the 440 wired into your board right out of the box.
