Guardians of the analog

Here is one that took a 3 times to get boxed up. I really hope to build this one last time as @Robert has plans of revisiting the circuit with intelligent relay bypass. So here is my backfeeder, the boss super feedbacker and distortion.
This build became a bit of a white whale for me. I built two different ppcb boards and had ppl noise present on both at all times. I even started a troubleshooting thread but no fix, and I was one of many with the issue. So in a moment of weakness I ordered the pcbguitarmania board that they stole from Robert while I was ordering my metal zone board. This one works...well 95% there at least. There is the occasional noise from analyzing the note, mainly on a long note decay but for the most part I really like what this is doing.
So what's this sound like and who is it for? The distortion is a modernized DS-1 like circuit that I actually liked so much I ordered the standalone defouler board. The main event is the feedbacker section. As a mainly IR/reactive load speakerless player, being able to fake feedback was awesome. While not perfect in execution or completely practical in all context, I think that if Robert does the relay bypass this will be epic. The momentary switch is less than ideal but it works for now. The feedback is limited to single notes, chords don't register how you would want and playing over held notes is not perfect but more an effect itself. But if you are going direct like me, this can be a great way to make some cool effects. I especially like the wobble that starts the feedback like it would IRL.
The build requires lots of components and I did teepee some bat46 and 4148s so get the originals diodes .9fv and a better output level. Other than that it's a big build that's crammed and requires attention to detail. For the enclosure I stuck with the backfeeder name because I HAD to use this design. Matte Black enclosure with UV printing. I have been wanting to use Magik (
) forever and this was the perfect project. One of her powers is energy manipulation...like back feeding power. Love how this one came together. I recommend this project with the caveat that you wait for the new version. Video clip showing the feedback during testing.
