If it still pops after you have a pull down installed, it’s your LED.
AMZ - LED Popping
How to stop the pops in audio from LED current surges when switched.www.muzique.com
Old thread but, used one on a SeaBed delay output and it stop popping instantly.
Check if there is DC voltage at the PCB output. (DMM black lead touch ground, red lead touch board output wire).
The Seabed has a 1uF Electrolytic as the DC blocking output capacitor. I've recently had some trouble with electrolytics from Tayda leaking DC so much that there's about 0.3~0.5v on the output, which causes a loud pop when activated or deactivated. In both cases where I had this problem, I replaced the electrolytic with a film (1uF MLCC, or in this case 100n film would probably work fine with no bass loss), and the pop was gone.

Came here for this. Built over 40 pedals in the last year and have just now encountered the infamous “pop” when hitting 3pdt on one of the Seabed’s I built. Thanks!Old thread but, used one on a SeaBed delay output and it stop popping instantly.

What did you use on the Seabed? Mine is having the same issue. Pops loud when engaging.Old thread but, used one on a SeaBed delay output and it stop popping instantly.

Also have the same issue on one side of a Paragon I just built, not as loud as the Seabed though, but noticeable. Thanks!
I built the Mercurial Boost & it is Silent as designed by PedalPCB, There is something else in this Build causing it to Pop!I am having some popping sound on the 3pdt switch on my Mercurial Boost. So I placed 2 x 1M ohm resistors on the in and out of the board. Same problem with my Chela.

Is this correct?

Right on man. Thanks again!!Same here, I've done a lot of PedalPCB building and it was the first time I had trouble.
I think the "Hot Cake"circuit, even if it is buffere, do somePop also.

Cool, Glad it was corrected.At one point there was no pulldown resistor on the output of the Mercurial Boost. (that's how the schematic was drawn)
It has since been added, so that's probably why yours doesn't pop but his did.
