Hi, all! I recently won a DOD FX72 Bass Flanger on eBay for a very affordable $30. It's a flexible, great sounding flanger, but I have a question on its speed function: The manual states the speed sweep is .8 - 8hz which doesn't mean much to me. I've noticed that the sweep doesn't begin to move until the knob is around 9 o'clock, and it maxes out at a rate that I'd consider "moderate" for most modulation pedals. Basically, there's no chance of getting faster rotary sounds out of the unit. Is this aspect of the pedal faulty? I know there are a few internal trim pots, but my searches haven't indicated that they are related to speed. It sounds like they may be tied to width, delay, and regen. Although it's a different unit, you can hear how fast the FX75 B gets in this clip around the 10 minute mark. Although they're obviously two different effects, they share the same manual, so it seems like some, if not most, of their functionality should be the same. Thanks as always for having a look. Any input is appreciated!
