Madbean! thanks for replying... My switch is a DPDT On-On-On switch, just checked my Mouser invoice to triple check.  I hooked it up to a 9v battery and the readings were much closer to the ones in your PDF.

I put the circuit on my scope. And these are the results:

LP-HP-BP   Range         Lo-Hi
----------------------------------------------
Left          Left(up)      L or R     =Signal
Left          Right          L or R     =Signal
Middle      Left(up)      L or R     =Static
Middle      Right          L or R     =Signal
Right        Left(up)      L or R    =Static
Right        Right          L or R    =Signal

To all you gurus out there. I finally got this Naughty Fish together.  My first attempt at etching, didnt come out that bad, next time I hope it to be better.  Having a couple issues.

in LP mode everything sounds fine.  But if I switch to HP or BP and have the range switched to UP (Left) I get lots of static.  Switchin the Range to down it goes away.  Also if I have the Lo-Hi switch on HI I get static.  I did a walk thru of every component (twice).  and triple checked my connections.  Turning the sweep pot also changes the static.  Here are my IC Voltages.

Power Supply Volts in 12.20v

IC1:
1.  3mv
2.  3mv
3.  0
4.  -11.37
5.  3mv
6.  2mv
7.  2mv
8.  11.91

IC2:

1.  1.38v
2.  4mv
3.  0
4.  -11.38
5.  4.73
6.  4.71
7.  9.22
8.  11.92

IC3:

1.  3mv
2.  2mv
3.  0
4.  -11.38
5.  0
6.  3mv
7.  2mv
8.  11.92

IC4:

1.  1.54v
2.  6.62v
3.  0
4.  .030v
5.  .690v
6.  4.59v

Thanks Jebus.. Im still a bit confused on you determine which one to use for specific functions.  But at least this will help finish my build, thanks!

Can one of you wise old owls help me figure out what type of pots I need
for the Gain, Peak, and Volume Pots on a Naughty Fish build.

and The Kraken Attack, Decay and Range pots.

Been reading about it but still cant grasp the Audio, Reverse Audio, and Linear options.
