FX75 Stereo Flanger

Two FX75s, from late 1984 (left, black text) and early 1987

The FX75 Stereo Flanger replaced the FX70 in DOD's lineup in late 1984. Featuring a Width control and two output jacks, the FX75 was much more versatile than its predecessor, but the flanging effect it could provide was still not very intense. That said, chorus-like washes of flange can be easily dialed in, and the FX75 can sound quite musical. The FX75 was produced with two color variations (see below) before it was replaced by the four-knob FX75-B in mid-1987.

• Controls: Speed, Width, Regen
  
  
• Black vs. blue text variants: The first FX75 pedals that were produced followed the FX70's color pallette (black text on a grey basecoat). In mid-1985 (around serial no. 331k), the text color was changed to blue, probably to make it better "jump" out of a display case to a potential buyer at a music store.
