DOD FX-65 Stereo Chorus 1990 USA Blue

The DOD FX65 Stereo Chorus was introduced in 1985. Because the two-knob FX60 Stereo Chorus was not discontinued at that time, the three-knob FX65 was likely intended as a "step-up" chorus for intermediate musicians, with the FX60 re-marketed as an "entry-level" chorus for beginners. Like the FX60, the FX65 is an analog chorus and uses a MN3007 BBD chip, but also offers a control for Delay Time and two separate output jacks for stereo output. The FX65 was manufactured until about 1997, when it was replaced by the final-series FX65B Stereo Chorus.

  • Controls: Speed, Delay Time, Depth

  • From the manual (1987, shared with the FX60 and FX62): "The ... FX65 chorus unit [is a] variable delay unit that gives the impression that more than one instrument is playing. It does this by delaying the sound of the instrument a small amount (4-6 milliseconds) and continuously varying the amount of delay ... [which] changes the pitch of the delayed signal. The delayed, slightly pitch shifted signal is mixed with the original signal and results in the chorus effect. ... The FX65 Stereo Chorus is a three-control chorus effect, offering adjustment of the sweep SPEED, the DELAY TIME, and the sweep DEPTH."

  • Technical info:

    • Specifications (1986): Input impedance = 500 k Ohms, Output impedance = 5 k Ohms; Maximum Input Level = 4V P-P; Gain = Unity; Delay Time = 2-6 ms; Speed = 0.2-6 Hz; Bandwidth = 40 Hz-16 kHz (dry), 90 Hz-12 kHz (delay)

    • Specifications (1987): Input impedance = 500 k Ohms, Output impedance = 1 k Ohms; Delay Time = 5-8 ms; Sweep Speed = 0.8-8 Hz; Bandwidth = 40 Hz-16 kHz

    • Notable IC chips: the FX65's circuit was revised at least four times, but always featured a MN3007 BBD chip driven by a MN3101 clock generator/driver CMOS chip; plus three op amps (TL022, TL062, 1458-type, or 358-type)

    • Internal trim pots: one or two, depending on the year; however, we do not recommend messing with trim pots
