Hello Herr Doktor,

Can you clarify something on the first sheet of Woggle mods?  

For mod 2 you've got the cathode of Vactrol VC1 connecting directly 
to +15 V.  Looking at that and the 555 control circuitry in the third 
mod,it looks like Vactrol VC2 is completely left out of the original 
Wogglebug design.  Is that correct?

The way I undersstand it, in the original design, the CV input based 
around Q1 drives both vactrols in tandem, one which controls the 
amount of the LF398s output going to the Smooth PLL, the other 
controls the 555 clock's frequency.  

BTW, thanks for submitting your mods... they look quite useful.

Also, I've wondered what kind of craziness a sync circuit on the 555 
would provide, such as the one on Rene Schmitz' VCO:

Has anybody tried this?
