[sdiy] Cry Baby, was: Unique sounding modules that can't have voltage control?

Following on from the Dunlop Rack Wah --
I bring you --- Akai Variwah guts.

Like all good Akai equipment, no service manual or calibration notes can be
found.

This Wah lets you assign a variety of modulation types to the wah cutoff,
sadly, only one at a time.
The PCB has some very clear markings on what some of the wire interconnects
are, which I assume are also meant to be test points.
I haven't used it in a few years.
If anyone needs any particular information from inside it, I'll be at the
same place as the wah later today.
