There is a basic DynaFlange preset I threw in for bonus fun in the 1000+ Naked Amps Tonepack for the Axe III, it is based on an older preset Dweezil made pre-Quantum era. I'm pretty fortunate to have heard version of this sound for 10 years know watching Dweezil play live and tat his Dweezilla music boot camps.
Key concepts to make a convincing DynaFlange preset:
1. hard stereo panning - it's TWO signals, one is dry and the other delayed slightly (and warbles)
2. use two different sounding amps panned hard, different cabs. One might be a 1X6, the other might be a 2x12.
3. maybe use GEQ before or after the amp on each side - left and right -- boosting/emphasizing/subtracting the opposite frequencies from the other side, to accentuate the stereo effect (like a comb effect in stereo, but without sounding phase-y).
4. Use a mono digital delay block with hard pan to one side, and volume block in parallel to delay (not series) panned the other way, after the amps, and set up the delay with a short ms time (maybe it goes from 5ms to 28ms in varying way) that is also tied to a modifier like envelope (or maybe pitch) --
one that knocks the delayed signal out of tune based on dynamics of how you play and hit the notes. With the real DynaFlanger, it gloriously whacks out of tune on one side while the the other panned side stays dry. That's one reason the sound is so huge.
Dweezil has used phasers, chorsus, rotarys on different sides of pan to spatially spread the sound out and make it even cooler.
5. Use a Wah in front - try it cocked and rock it slowly to accentuate notes. A real fuzz pedal doesn't hurt the overall effect/sound either!
M@tt may have other ideas...here is a screen shot of the Axe III one, but it's dated and he has used the delay/volume block in parallel trick now to make the preset smaller...
