A "select on test" resistor. You can also use a trimpot.
Just build it without this resistor, and you'll notice that the cutoff won't

go to very low frequencies. (The voltage drop over the diode is larger than
the drop over the OTA's Iabc input structure.) If you completly short
circuit
the diode, you'll wast much of your logarithmic potentiometer's range.
So just choose what fits right for you.

(Hey, I *said* this was a cheap design (;->) - use a real expo converter,
preferably the one from the original Wasp, if you want "ordinary"
behaviour.)
