FX25B Envelope Filter

FX25B Envelope Filter from early 2000, with original box

The FX25B Envelope Filter was introduced at the Winter 1998 NAMM meeting, replacing the FX25 Envelope Filter in DOD's lineup. Loosely based on the FX25 (but modified for the new "final series" chassis design), the FX25B's circuit also featured a Blend knob to help make it more suitable for use with bass guitar. The FX25B was retained when production shifted to China with the VFX series.
