Gudday all.
You might remember my Magnum Opus build. You might not. It can be found here: http://www.madbeanpedals.com/forum/index.php?topic=30309.0
Anyway. I'm having problems with switch popping noise, but I'm not getting it in the usual on/off switch - I'm getting it on both the other two footswitches, which basically just swap between 3 sets of pot and soft clipping options.
Both are 4pdt switches and have common anode tri colour LEDs clipped to 2 colours (red/green, red/blue), and I've put 47uf caps to ground off both 9v feeds at the switches following their 8k CLRs. As one side of the LED is always on at these switches, I don't seem to need to worry about another CLR after the cap. The On/Off LED is also a clipped tri colour, but it is set to red only, and I blew this one when I didn't use the additional CLR after the cap. After replacing the LED I used another 2k following the cap and all is good there (but I don't recall popping on that one anyway).
So... what can I do about this? I'm open to the idea that it's mechanical switch noise on these Tayda 4pdt and I may have to replace them... It's bugging me quite a bit as this is a killer sounding build...
