Doc et. al.,

I for one am very intrigued by these mods and eager to get a clearer picture
seeing the schematics. That being said, I hereby volunteer my services to
scan in the schematics. If going ahead with this is cool with Grant, feel
free to contact me off-list for a mailing address.

I took another look at a circuit I was thinking of building that also stars
the 4046, the "PLL Frequency Multiplier" designed by Scott Gravenhorst
(http://home1.gte.net/res0658s/FatMan/4046pll.html), and to my barely
electronically competent mind, it seems that this circuit is ripe for
cross-contamination with the Wogglebug, creating some sort of unseemly
monstrosity that I can hardly bring myself to imagine.

From what I can tell, the possible combinations are these:

The most obvious (and the one to add the most panel acreage) would be to add
the divide-by-12 section and the accompanying circuitry to make octave-up
and 5th-up harmonics for the Tone and Woggletone outputs. And perhaps make
some of the different harmonics generated by one of the 4046s patchable to
the signal input of the other? (I can't really conceive of how radically
this would effect the woggling, and thus if it would be worth it)

Or adding a switch to choose between the 2 phase comparator outputs on each
4046?

Adding the Damping section the Freq Multiplier to U3 of the Wbug (this may
be more or less equivalent to what the Woggle Time pot already does). Also
adding a CV input to this same bit of U3 (kind of like your mod #2, doc - I
think).

Or lastly, adding/combining the PLO F Min and Max pots to the
(dis)functionality of the Woggle Range control and/or R13 (not sure what
this control is actually called on the #3 Wbug - "Smooth Range"???).

The main caveat to all of this is that I have never played with a Wogglebug
and have only theorized about what the normal controls would do, let alone
any of the mods. These all may be mostly ineffectual or completely useless.

Comments?

Sorry if this DIY-related subject is OT for the list, let me know if it is
and I can cease and desist.

I am even sorrier that that last line came out in verse.
