On turning down the gain 2 pot to around 9:00 or so: The white noise can indeed be made to disappear. I also notice at this level subtle but audible clock noise on the repeats. Pedal will not self oscillate with gain 2 in this position (even w feedback knob maxed) is the other thing I made note...

@rurEEE thanks for your input on this. I've brought this up on the groupdiy forum in hope that we can get more suggestions. Discussing the white noise: - - - - - - - - I don't have an oscilloscope - but if this seems worth checking out and someone can measure next time they are in front of...

Today I attempted to further troubleshoot: •Pulled R23 and wired it to IC 4 The idea was to bypass the pcb traces that crossed w many others in case there was some sort of crosstalk. Unfortunately the same issue persists so I took a quick video. I play a bit at the end just to show that...

In the absence of another solution I’d like to start pulling up resistors to bypass parts of the audio path on the pcb via a wire. The idea behind this is that the white noise issue could be some sort of crosstalk. Does anyone have any ideas on where I might start with this? From my testing the...

@bean did you have a chance to look into this?

@Lorok yea dig that enclosure. @MichaelW I agree - love that it’s just like the old big box. Excited to hear any updates on a path forward!

Turns out that resistor was fine - I learned resistors don't always measure their inherent value when in a circuit. So I tried reflowing the solder and then just replaced the parts between test points 2 and 4. I also tried swapping out the MN3005 in IC9. All to no avail. Still open to...

I actually managed to isolate the problem to a certain area of the board between test points 2 and 4, and there turned out to be a bad resistor at R26 (measured 12k when it's supposed to be 100k). I'll report back if my noise issue is solved upon replacing it. It's a fun build! Make sure you...

Interesting about the 5k resistor. I'm not sure if that would affect the issue - there's also no 5k resistor in the older Total Recall build and every demo of it I see on youtube there is no white noise wooshing. I may have made some progress though - I realized the noise on mine gets...

I just finished building one of these and have the exact same issues you present here. Did you manage to make any progress? I noticed that turning the delay time down the noise goes away (I think because it goes up into inaudible frequency range). But I'm still scratching my head on whether it's...
