Up for sale, a 1987 DOD FX25 Envelope Filter in excellent condition and in perfect working order. A funky, shimmering envelope filter; the FX25 delivers warbles and underwater wah-wah weirdness alike.
The user-friendly controls lend themselves to experimentation, with Sensitivity and Range knobs. Sensitivity adjusts how much user input is required to set off the effect, and Range affects the movement of the envelope’s sweep. Rolling off Range leads to more low-end sweep, and cranking it up sweeps the high end.
This particular pedal is in good shape; the housing is built like a tank, with just a few minor marks on the enclosure as a whole. It retains the original trio of knobs with clean graphics.
