DOD FX25B Envelope Filter


  • Blend
    Controls the mix between the effect and the original signal. Count-clockwise gives you more of the original signal. Clockwise gives you more effect.
  • Range
    Controls the range of movement of the envelopes sweep. Counter-clockwise sweeps more low frequencies. Clockwise sweeps more high frequencies.
  • Sensitivity
    Adjusts the point where the effect's wah responds to your playing attack. With a higher sensitivity a smaller signal will affect the envelopes effect. In other words, with a higher sensitivity you don't have to pluck as hard to make the effect audible.

The FX25B is the reincarnation of our original envelope filter. You still get that great automatic wah sound, but we've taken it one step further by adding a blend control making the FX25 equally responsive to both the guitar and bass guitar.
