[sdiy] Unique sounding modules that can't have voltage control?

[Mike Bryant]

R5 C4 VR1 also form a variable frequency element as well as controlling the feedback level.  Hence the waa effect.

Do you count a wahwah pedal as a module? You get them built as modules!

The way that the pot adjusts the centre frequency of an LC bandpass filter is a bit magical, and cannot really be replicated by any CV circuit.

Looking at this description of the Cry Baby:

It seems to me that the pot just sets the amount of feedback. This could be easily replaced by a VCA. Am I missing something?
