Help regarding Bad Monkey mod

Hi all
Have done a mod on my Badmonkey pedal, i read that removing the .047uf capacitor found at c5 on the circuit board removes the mid range hump , i did this mod and now although the mid range hump is gone the treble control on the pedal does not work,it is like the treble is maxxed regardless of how much i have the treble control turned up.

There are 2 possible reasons that i can think of why this would happen, 1st is that i have cooked a component with the soldering iron when removing the capacitor, the 2nd possibility is that the .047uf capacitor controls the treble control and removing this capacitor has resulted in the treble being maxxed , what do you think?

Well, the capacitor is a part of a resistor / capacitor pair that act as a tuning filter. Depending on how they are arranged, they either act as a low pass filter or a high pass filter. You should have replaced it with a different cap (having worked out which one you need) to set the frequency you are after. Removing one of the pair will just leave the resistor on it's own and that could easily affect the next filter on the circuit...which has probably happened. Did you bridge the two holes where the cap used to live? If not...the break in the circuit (which used to linked by the cap) has probably caused the problem. Try soldering a small wire link between the two vacated holes.

Thanks, i will replace the capacitor (have just looked up the correct value cap ) and hopefully that will work
