Wah-Wah true bypass "pop" noise

[quad]

Hello again!

I'm not a real pro when it comes to electronics, so I'd appreciate some help with this wah-wah pedal "pop" sound I'm getting when it's turned on/off.  I have modified my GCB-95 with true bypass and an LED. It seems that the true bypass mod now causes the pop. The input/output capacitors leaking some DC when discharged, if I'm not wrong.

I've read you have to add ~ 1Mohm caps on input/output capacitors to ground (input/output jack sleeve?) to bleed the DC to ground.


The capacitor I've circled in the picture is the clean input cap, so I have to solder the resistor in between the cap and input jack sleeve?

Besides, I'm having a hard time locating the output capacitor, with which I should do the same. (soldier output cap to output jack sleeve).

Please correct me if I'm wrong and help me locate the output cap.

Pull-down resistors don't work that well in wahs i noticed - it causes the hi pass filter (the wah itself) that emphases the click. I couldn't get rid of the pop so i did this: wire the 3PDT switch the way it grounds input and you will love it. Forget about 1M resistor thing.

Hmm, interesting...

How should I wire it though? This is my current setup.

Look here:

You will want to use Layout #5

Good Luck

I have made a mistake somewhere because there's no bypass signal. The effect works though:

The only thing I see wrong with the layout you posted above is the LED. You should connect the LONG leg of the LED to the resistor (going to the DC jack) and the SHORT leg should connect to the 3PDT switch.

If you get effect but NO clean bypass signal then your problem could be the 3PDT jumpers or the 3PDT switch itself.

Good Luck

Have a look on andreas' site about adding an led to a wah - http://stinkfoot.se/archives/553

hope this helps !

I used this wiring diagram:


The effect works, but when I switch it off there's no bypass signal. I soldered the ground of, which is connected to input jack sleeve, and then the bypass signal starts working. So where does the ground exactly go to?

Alright, I decided to completely remove the buffer (6 components in total), using this guide http://stinkfoot.se/archives/546

I wired the pedal accordingly. The effect and true bypass works now, but the "pop" is still audible on high gain settings.

Is it suppose to be completely silent? You can barely hear it on clean settings though.

UPDATE:

I removed the LED circuit - the noise is barely noticeable at all. Now I have to fix the issue with the LED.
