DOD Envelope Filter 440

Classic Envelope Filter Reborn

Quacky, quirky, and expressive as all get out, the DOD Envelope Filter 440 is one reissue pedal guitarists everywhere eagerly anticipated — and now it’s back and better than ever. On its own, the DOD 440 pick-attack-activated slow filter sweeps give you a kind of funky auto wah effect, and it’s a real beast when you couple it with overdrive. The Range control lets you dial in which frequencies the filter sweeps, so you can avoid muddiness or harshness. But it’s the addition of a bipolar Voice switch that makes the reissued Envelope Filter 440 so cool, which allows you to select whether the rise or fall of the sweep gets emphasized. And whereas the Up setting gives you the classic 440 guitar effect, the bass players here at AJ’s Music & The Music Man really dig the subterranean dive you get from the Down setting.
