serious popping problem, explained with details

Postby abakuzam » 25 Feb 2014, 11:02

Hey everyone, i have a serious problem with the switch popping. I used three different switches (links below), i'm using this pitch pirate layout; http://imageshack.us/photo/my-images/81 ... ayout.png/

i tried dpdt with millenium (bs170) with this layout http://tagboardeffects.blogspot.com.tr/ ... enium.html, i tried with no leds, i put 2,2 m resistor ,(also tried 1m) circiut input and circiut output but still popping. Feeding with 9v battery, and i dont have a proper gorund in my home, so my amp (ibanez tbx30r) a little bit noisy (even celan tone when gain:9 o clock and volum: 9 o clock) but i tried other amps and places, still pops. What do u suggest i tried all with these three switches, i thought switch's fault but i changed them a couple times! please help!

I don't see an input cap in this layout?

Try putting a 10nF cap in series with the input.

Once you do this, you may still have a pop, but any of your approaches should solve it. (I recommend the 2m2 resistor to ground just before your new input cap).
