You have somehow missed build note 7..
that's right! i thought that if i'm using the REV LOG potentiometer i should leave this pad as is...
now all is good

i have a great flanging effect.
i still don't know how exactly to set up RT3 to the "right" set up , something there is not linear and kind of confusing as the trimmer starts to effect the clock in a certain area and then it get to have a 'intermittent' effect on the range pot. i'm not sure how to describe it
what should be the right setup with RT3? what should be the resistance there?
Great! So what capacity you have at C17 now?
Ok, so because i'm using this effect as a part in my DIY modular synthesizer i want to give it some more options.
so i decided to have a 6 position switch with different capacitors this can be useful for making a subtle flange
with strings or a total chaos with a drum machine for instance. i found out that when i'm touching the leads of C17 i'm
changing the range in different ways so maybe i'll add a touch pad to that section...
i'm also going to try to add some vactrols to the circuit in order to have CV control over the pots.
i guess that the experiments can be endless with that circuit...
the caps i'm using for C17:
1nf (the more 'standard' effect)
1.1nf
2.2nf
3nf
10 nf
27nf (meteor crush effect

and i'm still trying more values...
BTW i found out that when using the NJM4558D i got a nicer sound . i also found differences between different 3207 ic's.
Thank's a lot for this great project!!
