FTelettronica Envelope Filter Pedal

The FTelettronica Envelope Filter is a dedicated bass filter pedal that reacts to the way the instrument is played, giving you that familiar “quack” and sweep associated with classic envelope filters. Play lightly and the effect responds differently than it does when the strings are hit hard, making it a lot more interactive than a fixed filter. It's a natural fit for funk, soul, R&B, and anything else where a bass line needs some movement, but it can also be pushed into more pronounced and unusual filter sounds.

The big appeal here is the dynamic response. The filter follows the attack of each note, so the sound changes along with the player's dynamics rather than simply applying the same effect all the time. That makes it especially fun for slap and fingerstyle playing, where changes in attack can produce noticeably different sweeps.

Handmade in Italy by FTelettronica, the Envelope Filter has a compact footprint that makes it easy to add to an existing bass pedalboard. It's a straightforward option for players looking for some extra personality and movement without getting into a complicated multi-effect unit.

Features

• Bass-specific
• Controls:
• • Threshold (Sensitivity) – adjusts envelope sensitivity, defines how strongly the input level triggers the filter sweep.
  • Attack – Sets the rise time of the filter, introduces a delay to let sweeps build gradually
  • Emphasis enable more or less pronounced filter peak
  • Up/Down (Reverse Sweep) allows the filter to open downward instead of upward—i.e. louder attack lowers cutoff instead of raising it. Useful for unconventional, reversed wah effects
  • Filter Range allows switchable filter cut-off ranges—you can switch between lower-frequency sweep vs higher-frequency sweep for brightness or funk depth
• Dynamic, touch-sensitive filter response
• Expressive envelope sweeps
• Classic funk-style filter tones
