I did the same thing on my Mr Roboto, I was pissed lol. thank you for following up! I moved and am neck deep in opening a brewery so I haven't touched my iron in a few months, but this gives me a reason to dig back in.

ah ok, mitigating ground loops makes sense. would that apply to any mixer? i often run my guitar pedal chain directly into my SSL big six, as well as bass through a preamp pedal.

yeah, exactly. is it because it's such a low amplitude signal?

So I was watching some video on DIY synth module circuits on Moritz Klein's channel, and he added a ground lift to the circuit at one point to reduce noise and get an arpeggiator to track pitches better (pretty sure that was its role, I'd have to watch back). I've seen ground lift toggles on...

Man, I really feel these vibes. I'll check out the clip when I get home. I've only built two compressors but have spent a ton of time with studio compressor plugins, for whatever it's worth.

ah ok, I'll experiment a bit more when I'm back home. I got very fixated on analyzing the circuit itself early on so I may just not have played with the knobs enough. one of the most frustrating/challenging aspects of this hobby has been knowing "is this supposed to sound like this or is it...

yeah that's the sound, and it's definitely something along those lines, but it makes the noise even when no input is connected (or the guitar is muted). it's constantly starting from one pitch, going down to an almost inaudible frequency then goes back up to the starting pitch. my hypothesis...

many things have transpired since a month ago: -sanded the inside of the enclosure (the only one i've ordered pre-painted); no change -tried shield wire for the input; no dice -reflowed the jacks, TL072 socket, CD4069 socket, CD40106 socket and all I/O wires my conclusion is that the CD4069...

ok well i hadn't thought about the crow crew in a LONG time, so thanks for dusting that memory off and giving it a nice refurb. my first thought is that the cigar tip is a red LED, but that's neither here nor there...

are electrolytic caps a more fussy component? I hadn't considered them as part of my QA (looking at you Super Heterodyne Receiver...)

tag yourself, I'm this saucy little tenpiece 😍

very clever!! death by audio vibes to utilize a unique or oblique component. I have a vague recollection of some random diy project that used them for defeating facial recognition tech, but don't quote me on that.

ok I gotta hear more about the infrared LEDs... how'd you think to try it?

This was a pretty easy build, with the only exception that I soldered the pots in three stages rather than trying to align all 27 pins to the PCB at once. It sounds cool, but I do get a cyclical whooshing sound in the background while everything is maxed for each filter (intensity, resonance...

Hi all, the second of today's three builds went swimmingly, as I had done 90% of the work ready and just needed to slot in 8n2 caps, connect the wires and box it. This is the first time I've built a repeat, but this time I followed the BoM exactly instead of making a few subs out of...

Hey all, this was my third build of the day, and I knew it was probably too much, but I finished the Nugget Fuzz this afternoon. Only issue is that there's no sound. It passes clean and clear audio through the C-buffer when the circuit is off, but when I switch it on I get a lit LED but no...

ok this gives me some hope then!!! they have NOS chips on stompboxparts so I'll pick some up.

What was the issue you were having? i think a bad batch of CD4069s might be why my super heterodyne receiver isn't working, i get a weird divebomb sound which i think is noise going into the CD40106. good job trouble shooting, nice build!

this is good to know, i think i have some germanium ones not schottky. thanks!
