DOD FX25 Envelope Filter – Pre-Owned

The DOD FX25 Envelope Filter is a classic envelope‑controlled filter pedal from DOD’s original FX series, first introduced in the early 1980s and produced until the late 1990s. It creates a dynamic “auto‑wah” effect that responds directly to your playing intensity: harder attacks sweep the filter higher, while softer notes stay more subdued — giving you expressive, funky, vocal‑like tones without moving a foot pedal.

Straightforward and intuitive, the FX25 features just two main controls — Range to set how wide the filter sweep travels, and Sensitivity to adjust how easily your playing triggers the effect. This simplicity makes it ideal for players who want organic, touch‑sensitive filter sounds without needing to dive into complex menus. It’s equally at home on guitar or bass, adding classic quack, funk, and dynamic movement to your sound.

Now discontinued and often found on the second‑hand market, the FX25 remains a cult favourite for those seeking vintage envelope filter character and simple, musical interaction with their playing.
