The DOD Envelope Filter 440 Pedal is a dynamic auto-wah/filtersweep effect that responds organically to your playing, adding funky, expressive movement to your guitar tone without the need for an external expression pedal. Its classic envelope control lets the filter open and close based on how hard you pick, giving you everything from subtle vowel-like tones to bold, quacking sweeps that make riffs and grooves come alive. Simple, intuitive controls let you shape the sensitivity, range, and character of the effect, making it easy to dial in funky rhythmic patterns or dramatic filter accents. Built in a rugged, road-ready chassis with true bypass switching to preserve your core tone when off, the 440 delivers classic, touch-sensitive envelope filtering for players across genres.
