Hey Brach, thanks for the update. I’m in Milwaukee, so I might be able to swing down to Chicago some day to have you take a look at the pedal. It’s certainly not an emergency, but I will get in touch if I am able to find my way down there.
Brach, I’ve tried all of the trim pots and there seems to be no difference. The sound is especially more pronounced when I have other pedals in the signal chain, but it is the same if they are on or off, and whether the Quaverato is on or off. Even with nothing else in the signal or power chain, there is still the PWM leak.
Brach, as far as the power supply, I have tried isolated power supplies (truetone CS7) daisy chained, or standalone wall-wart powering just the Quaverato, same results. I will mess around with the trim pots tonight.
Thank you for all of your help and patience, Brach. The Quaverato is going to be going on tour with me in March.
Alright. I swapped around the bridges and bridged the IC to the LDR. Everything seems to be working well now! I do notice it is a much darker tone than my bypassed clean tone. Will I need to re-calibrate the trim pots, or is there another issue?
Brach! These seems to have done most of the trick! I jumpered R4 to TP4 and R5 to TP2. I am now getting tremolo and all the knobs seem to be doing something. I do not, however, seem to be getting the “Harmonic” effect.
Now, I don’t seem to have a good connection at JP3. I believe my pads are burned past the point of soldering anything to them. When I tried to attach a small piece of wire, it didn’t have anything to adhere to.https://drive.google.com/file/d/1enTMnNzErKcSwl3Mak0h9ykUjPVLoGU1/view?usp=sharing

https://drive.google.com/file/d/1enTMnNzErKcSwl3Mak0h9ykUjPVLoGU1/view?usp=sharingI have probed TP1-TP4 with tweezers with the effect engaged, depth turned all the way counter clockwise. I get no sound at all from them.
I meant when I bridge between the second lug of the volume pot and the capacitor the bypass LED stays on by my bypass signal is coming through as well without any tremolo effect. It appears to be running through the circuit, because the volume pot will effect the volume of the bypass signal. I don’t know if this is relevant at all, just something I found was happening.
The relay appears to be working, continuity across the pins you described.
Nothing happens when I touch TP3 or TP1.
The noise comes when I touch the leads of VR10 and R4 and R5.
When I touch the leads relay lead closest to the edge of the board on the side of the power LED, I get a slight static. I also get a high-pitched squeal when I touch the legs of the trim pots on the input-side of the LDR.
One other place I get sound is when I touch leg 2 of the volume pot with the lead of C1 at the same time. I get full bypass tone and the effect stays on (relay does not switch off.) None of the other pots do anything, but I can drop the volume of the input signal with the volume pot (full volume remains at unity.)Alright, I have poked and prodded each component, I have gently nudged and moved each pot trying to find anything that might be shorting. The only difference I get is when I touch certain legs on the ICs there is extra static. I have not been able to get any effect or even dry sound when the effect is engaged. I am beating myself around the head, because I can imagine it is a very simple thing that I am missing.
