FX75C Stereo Flanger

FX75C Stereo Flanger from late 1998 or early 1999, with original box

The FX75C Stereo Flanger was introduced at the Winter 1998 NAMM meeting. Like the FX747, the FX75C was largely based on the FX75-B's circuit (with an analog MN3007 BBD chip, but modified for the new "final series" chassis design), and the FX747 and FX75C were identical in all but name. As DOD's only flanger, the FX75C was retained when production shifted to China with the VFX series.

• Controls: Level, Speed, Depth, Regen
  
  
• From the manual:: "The FX75C delays the input sound and then mixes the delayed and original sound together. The DELAY time control adjusts the amount of delay time in conjunction with: the WIDTH control which sets the range through which the delay time may vary, and the SPEED control which adjusts the rate at which delay time changes. The REGENeration control adjust the height of the comb filter peaks by controlling feedback through the delay circuitry. The REGENeration control allows the adjustment of the effect from very subtle to very pronounced."
