orange squeezer input cap?

[guavatone]

I just want to make sureof this.... Which is the input cap people talk about changing?  ggg schematic shows input>.047uF cap>resistor>.047uF cap to oopamp.  Do I change both caps or just the one before the resistor to a lower value?

Thanks in advance

The input cap is the one in series with the input resistor  
The first one after the input.

Thanks I wasn't sure if it was closest to the input or the opamp
