My board is just like this, just yellow instead.

It's mean't to be a copy of EHX Deluxe Memory Man , Which is ECHO DELAY CHORUS VIBARTO

At all possible to change chips and have it more like Chorus/Flanger Polychorus ?

The clock rates required for flanging would be MUCH faster than what the circuit provides for,  You would also need to drop the number of stages of delay considerably.  Presently, there are 8192 stages.  You'd probably want 1024 stages.  That change is much bigger than what you might get by tapping the signal after one MN3205 rather than two of them.

Yeah this board is 9v and the Delay time that it's suppose to offer according to the box it's 500mm and then the manual says 450mm.

Unless just unattach the red and black wires and attach awhole new made up board ?

Just use the casing etc of this thing.

Is it possible ?

And here is the inside of the POLYCHORUS XO

Oh yeah , anything PAST 5 for the feedback on this VTM it's beyond annoying it's like a UFO Launching/rumbling into space :icon_lol:

So yeah the feedback knob is pretty useless on this , Possible the chip used in this is too powerful for that function?  I doubt DELUXE MEMORY MAN turns into a UFO Launch/rumble.
