SOLVED Glory Hole Switch Pop

[Locrian99]

I’ve got a glory hole i built and its got a switch pop
Thing going on.

Apparently I’m not the only one who has experienced this. As theres another thread where two are mentioned having the problem. One of the more popular boards I imagine, im assuming they all havent had switch pop…

I tried the fix in KR sounds thread and it did not fix it. I removed the ground from led, so it is no longer coming on. Doesnt fix it. I would describe it as a squeaky pop. And it almost seems like it builds up. Rapidly pushing the button seems like it gets quieter…

Any suggestions?

Sounds like a leaky input or output coupling capacitor (C1 or C9).

Since C9 is electrolytic I'd suspect that one first.

are electrolytic caps a more fussy component? I hadn't considered them as part of my QA (looking at you Super Heterodyne Receiver...)

You can bet on that. I REALLY recommend you change the 2.2uf for a 1uf non polarized

Yes they are. 90% of the popping issues on pedals are caused by leaky capacitors (don't quote me on that number)

Wouldnt the cap and pot be forming a filter though? No fear of changjng that?

Edit: oh the frequency is like inaudible, why choose a 2u2 there then? Seems odd.

This is what I did that seemed to take care of it. It definitely has to do with the LED in the circuit though. Take it out and it went away.

Yea that didnt change it for me.

Is the pedal isolated and on its own, or in between other pedals/circuits?

I'd rather put a 2µ2 non-polarised box-film cap in place than go to 1µF.

all by its lonesome. Hasnt made it past the test bench hey joe renditions (we all have our test riff
Right

In sure most everyone has built this to spec, i assume theres been a couple hundred of these boards made at least. While it might not be the “ideal” component im sure everyone who out a polarized 2u2 electro there isnt getting pop so im
Going to try another.

 

[Locrian99]

And interestingly enough there is still a bit of pop. Not as bad though. Maybe ill try an mlcc and see what it does. I dont have a folm that large.

I just said 1uf because is a more standard value to have in stock, but 1uf Is usually more than enought tô let all the low frequencies pass.

Well i tried swapping in a new electro thinking maybe it was bad…. Nope

Switched the input coupling cap… nope

Put a 1 uf film cap in as suggested…. yes

These are the cheap tayda electros (which id wager at least 50% of us use these). And i tried two so maybe bad batch? Ive got to think theres at least 10-15 forum users here who have built these with the same caps and complaints really…

Thiught maybe my cable is causing something or my amp…. Nope i had given yhis pedal to a friend and he is the ine that brought it up. Anyways. Guess when i build another one. Ill buy a higher grade cap and see if it makes a difference.

It happens even with pricier caps. Spring for the Nichicons at least

awesome, man, glad it worked!
