SOLVED Switch popping and noise galore with Bootleg and Glory Hole

[KR Sound]

Here’s what I’m building- dual Bootleg and Glory Hole with order switcher.



I tested them both prior to assembly without LEDs in the test platform and they both sounded great.

Now I put them all together and I’m getting switch pops on both and crazy noise from the BL

I took them both out, removed the LEDs and put them in the test platform with the footswitches attached.

BOOTLEG:
Bootleg still popped and buzzed at high gain and volume.

Removing the LED gets rid of the popping, but there’s still high gain buzz. I even swapped out all the ICs just cause.

GLORY HOLE:
Changed the footswitch, changed LED, removed LED, and still have popping. The only thing different from the BOM is an 18k resistor for the LED.

There’s not much to this and I’ve built it before without any issues. I’m about to swap out the caps to see and then try the approaches on AMZfx perhaps.

What am I missing?

I had my friend check the Glory Hole I made for him last year, and it’s got a bit of switch pop as well.

Interesting. I just built a glory hole and am having switch pop issues as well. Never had this with any thing else before. I’ll try the resistor.
