Gravitation Reverb.. Take 2

[swelchy]

Built for a friend last week and I could never figure out why it wouldn't work.. Everything was correct. built a new one with all new parts and it fired right up.. Only issue is an annoying switch pop.. not sure if it's something normal with the circuit or a problem. My soldering and wiring is pretty clean on this one.

Glad you got the second one working, I love this pedal. Great artwork

Are these touching each other, Cut off excess wire & solder!:

They are close but definitely not touching… I have a magnifying lamp to inspect

Sometimes electrolytic capacitors leak some DC, my guess is that’s happening on C11. Even though there’s an R pull down, the cap leaking is enough to keep a DC offset on the output of the circuit, causing the pop when switching.

I’d try replacing that cap with a film box type 1u (which is pretty big) or a 1u MLCC (multi-layer monolithic ceramic capacitor). I’ve had this exact problem a number of times, fixed by replacing the cap type

That’s the happiest 3PDT that I’ve ever seen.

For the Popping issue, Try replacing C11 with 1uF Tantulum cap (Check Polarity is correct) & if the problem still exist, try changing R12-100K to 10K.
It's a recurring issue with the EQD design!!!

That’s the happiest 3PDT that I’ve ever seen.

Specially with the extended ends!

Ironically enough I put the back on the enclosure and it magically stopped popping when engaging it… All is well. I did some recording to send him a file of what it sounds like until I can meet up with my buddy and give it to him. .. I did end up trimming and resolderering some of the messy switch wiring… but that only cause y’all gave me a hard time …

Glad it’s working well, if the popping issue comes up again, you know what to do.
