Less than $1 each. Not much of an increase in 43 years.e.b.a.y
Sounds vaguely like a twin-T.Its just a waa waa pedal.
I have seen it done with 3 resistors and 3 capacitors to get the phase shift.
Then use a high gain transistor for the gain to make up for losses.
Make one of the resistors variable to get the waa waa variable frequency.
