DOD - FX70 Stereo Flanger

Postby TubeDude22 » 18 Feb 2017, 19:06

I have a nice old DOD FX70 Stereo Flanger that uses the MN3007 and MN3101 chips. What I dig about this pedal is that with the regeneration turned all the way down, it has a sweet chorus-like tone. I want to get more of that. Are there any mods I can do to this thing to make it less like a "flanger" and more like a "chorus"?

Schematics are scarce for this but, I've attached what I could find on the web. Thanks for the input.

Did you ever figure anything out with this?

looking at the schem that 500kohm pot looks like being the regeneration/feedback knob. try working on that 62k resistor. I suppose putting a higher value will limit the feedback signal and give you a more chorus sound. What you could also do/try, it's put a switch to cut that feedback loop.
