I own two Ibanez EM5 delay pedals. I have read that upping the flip flop capacitor from .001 uF to .010 uF would solve the switching problem on these line of pedals. This will be my first mod ever to an effects pedal but my soldering skills is quite good. The problem is I do not know how to trace a PCB. I would like to ask for everybody to help me point out which  .001uf  flip flop capacitor should I replace? I have a few pictures of the PCB below. There is a cluster of  102 caps on the PCB( inside the yellow circle). Thank you so much.

The schematic is infinitely more helpful than pictures of the board.

I'd guess it's C27, but with the schematic posted, you're likely to get someone in here who knows better.

Thanks, I also think it is C27 . I guess I need to learn how to read schematics. Thanks for the link!
