Univibe into a phaser on a switch Mod ??

[strassercaster]

hello I just finished a   univibe on stripboard . I want to use a 4pdt to be able to switch  the four phasing capacitors from  220n,15n,4.7n and 470pf to four equal values. I want it to be a normal phase pedal without the warble as well. i was wondering where to start for proper frequncy and cutoff. i know there is a some math involved to get it right. I could just experiment and I will but what would be a good starting value? i am going to try 47n like in a phase 90 first but maybe smaller idk. Any suggestions what might work best.

i have done the opposite of this to all three  phasers i have built . the phase 45 90 and small stone. Having univibe caps on a 4pdt switch as well.They sound pretty cool but not near as good as my  univibe clone . I am hoping to make that super  lush univibe do super lush normal  phase as well at the flick of a switch.  .Anyway i wont get around  to it for a couple days just trying to get a plan of attack. thanks in advance

I just read a few posts about similar questions. I would love a lesson on how to calculate this out. I am more confused now after reading some other stuff.Is it possible to have 4 of the same caps replacing the .22 .015 .0047 and .ooo47 caps. would i have to have two different sets of caps ? thanks hopefully this will sound good if done right.

I also have another question. to get a good phase on this ill have to have the vibrato switch on as well correct?
