Vibrato / Tremolo

Hey,
Does anyone know how I could add a speed controll to this pedal?

Thanks Guys

It's over on the lower left.  If you wanted manual control via a foot-treadle, simply install a 1/4" phone jack and run the 2k2 resistor to the hot lead of the jack, have the hot lead of the jack go to any lug of a 25k pot in the footpedal, have the adjacent lug of the pot go to ground, and run ground that back to the ground connection on the jack and the Wobbletron ground.

That will let you do the speeding up and slowing down with your foot.  That's what you wanted, right?

What do you think that 25K "Freq." pot does in the bottom left corner :?:
