Problem using Wicked Switch with Tube Sound Fuzz

[bubish]

I am working on building a TSF with The Tone God's Wicked Switch (http://www.geocities.com/thetonegod/switches/switches.html), and have run into a problem.
When it is switched to clean, it works fine. When it is switched to use the effect, however, all I get is noise (mostly a farting sound, and if I hit a string, it sounds like sound effects from the Atari game Berserk). 

I hooked the jacks directly to the in and out of the effect, and it works fine.
I tried using the switch with the effect disconnected, and again it works fine when switched to clean.  When it is switched to where the effect would normally be, a very faint bit of signal still came through.

LED behavior is normal.
I am using a 4049 with the cd4066.
I have quintuple checked everything and it appears to be wired correctly.

I'm still a noob, so forgive my misguided speculation, but is the TSF output just too much for the CD4066 and causing it to distort?
Any help is MUCH appreciated!

Just skimmed thru your post.  Have you biased the ins and outs of your CMOS switches?  If so, check the solder joints/connections.  If not, read GEOFEX on CMOS switching.

I replaced the 4066, as the one I was using was mined from an old CD player, and it seems to work fine now (I did this before reading this reply).  I had assumed it was a bad chip (being old and going through a desoldering), but I also didn't know anything about biasing the CMOS switches.  Could it it be then that the old IC is good, but the new one just happens to work better without biasing?
In the meantime, I will read the GEOFEX article.

Thanks!

Biasing may or may not be an issue.  If you AC couple a signal to a switch and its input is left 'floating', then it's possible (with a large signal) to pull said input past one of the rails.  That would bring one (or more) of the protective diodes into conduction.

More likely, in your case, that you damaged the chip when desoldering.  Protective diodes are easy to fry and may account for the problem you had (if you damaged the diodes through overheating).

Do the numbers on your ICs end in UBE, as in CD4049UBE?  If not, they need to, IIRC.
