Here is a pretty easy workalike:

Use a copper plate for the antenna, replace a pot of your choice with a Vactrol and probe away!

The Probe series ones are the only ones that really seem interesting to me... though the Fuzz Probe doesn't seem useful as anything other than a weird noise pedal.

No they are not the same. I have an original Volume Probe. The one with the thick coil of wire that acts as the antenna.
If my memory serves me, it has a single 14 pin DIP, two transistors and a VacTec opto-coupler.
No offense to topopiccione, but the ZVex system seems much slicker and streamlined.
My guess is that it uses a 4046 Phase Lock Loop. That said I'll also mention that I went to art school and have no formal training in the subject, it's just my intuition.

I don't suppose you could provide some pics of the Volume Probe so maybe we could figure it out?

Yeah, pretty please!
Oh, I know you.... Is this: http://super-freq.com your site soggy?Great etches, best I've seen!

A 4046 ? this would be tooo complicated, I think.... At the first view "R11" seems to be a capacitor and the IC seems to be a 4011 or 4093. The rest is a.... right....: SHO.

There´s a sucker born every minute - and too many of them end up in the bootweak pedal biz.

R11 is a light green 1/4 watt resistor standing on end. The other resistors are 1/8 watt.
If the IC is just a logic gate, it could be set up as a simple square wave oscillator. The frequency would determine the brightness of the LED in Vactrol?

As far as I remember I wrote some postings above:

Check the VCC pin on various candidate chips and see how they line up with the diagram.
