Just confirming, would this be resolved with the non-latching simple relay?

For what it's worth my spirit box that I finished a couple of weeks ago doesn't have a pop. There is a barely audible click when engaging and disengaging that I honestly only caught after recording a quick demo looking for it.

Same for mine, it’s just annoyingly noticeable on the high gain channel. If I could mitigate it altogether I’d be stoked.

Test for voltage on your output, your 1uf output cap may be leaking. If so replace it with a film cap!

Unfortunately, it isn’t in my possession anymore. Just researching solutions for future builds.

Anything with an electrolytic cap on the output that pops, that’s where I start if pull down resistors are already in play.

Good to know. Beyond that, would the Simple Relay Bypass also correct the switch pop?

I'll try a film box on C2 and a 10k on R7 next build.

There’s another thread with some substitute values for volume loss and such. Search the board so you can make sure you know all the hints.
volume drop mod is great but to be honest the increased dwell mod to make it self oscillate is not worth it.

Still getting a noticeable pop on high gain amps with a film box on C2 and a 10k resistor on R7. I have both socketed in case there are other suggestions.
Gotta go back to my original question for this.
Would a relay prevent any noticeable pop?
Any help would be appreciated.

Just replying to get notifications on any workarounds, of course after more use and after I posted that demo it's bothering me more

That leads me the LED…if you take it out does it still pop?
Danbieranowski

Yeah it still pops without the LED. Here’s a black screen video (I just set my phone on my desk) demonstrating the sound. On low gain it’s not really noticeable but high gain and it pops out.
I hate to harp on this, but can anyone answer whether a relay switch would help with this? No one has spoken on that as a solution and I’ve read it’s helpful when switch pops are an issue.

Unless it's the switch itself causing the noise, using relay bypass might not help, and in some cases could even make it worse.
A relay module that mutes the signal when switching could help but I've heard just as many complaints about the momentary dropout in signal as the switch pop it's trying to correct. It just depends on which one bugs you more. Some are probably better than others, and it likely depends on the circuit you're pairing it with.
A buffered bypass of some sort (Boss / vintage Ibanez style) would probably quieten it right down. (ducks for cover)

Not totally sure the best way of testing this, but if I use a probe on the IN (wire to board input) labeled spot on the 3PDT wiring board soldered to my switch, there is no noticeable pop when engaging and disengaging the pedal). If I put the probe on pin 15 of the PT2399 I hear the pop when I engage and disengage the footswitch. If I put it on the OUT (wire to output Jack) I do hear it pop when I engage and disengage.

I am 100% okay with buffered bypass. Just want an effective way of getting rid of the pop.
