I was excited to see this heading as a friend is having the same issue with his build, but without knowing where either 2 maybe solder joints were. Oh well.

i'm having the same EXACT issue, not sure if its a board thing or not, i recently re capped and replaced the IC1 in my dream fuzz, it had been working perfectly and then one day decided it would do the same exact thing, loud squeal, no rhyme or reason. kept it on the bench and would play...

i'm having the opposite issue, i get a loud squeal with mine, self oscillating high pitch squeal. turning it on obviously amplifies it, took the thing apart, replaced the 4558 with a fresh one, changed all the electrolytics, checked other points, replaced the diodes, etc etc. works fine for a...

I'm actually having this same problem on the current revision. Built it and it worked like a dream, zero issues or noise. A few weeks ago i turned it on and there's this epic squeel coming through the pedal. the effect still works, but if i'm not playing the squeel comes right back. I've changed...

Hey man, that would be amazing. DM me with pricing and such and maybe we can figure something out. Another question I didn’t ask myself, does the 8950 amplify the signal it receives at all?

I really do appreciate all of your help. It’s either a grounding issue on the board itself (a trace going to ground that shouldn’t be) which I ne’er stand happens, or it’s the chip, (which IS doing its job. Prior I ordered 2 of the B3k boards, one came out flawless, and one has a ground loop I...

I did not get any extra chips as they're hard to find and this is a one off for a friend, but again I'm stressing the signal drop on R5 before it gets to Pin 5 on the 8950. the effects do work, the sound is just super low and muffled.

thanks! yeah, the form we formatted my post and smooshed it. so again, the signal drop/loss is occurring where R4 and R5 link up, but the drop is only occurring at Pin 5 coming from R5, the signal from the op amp is good all the way to this point...ghost in the machine.

audio input volts don't seem to match up, although, I'm not very good at this, here are my voltage readings per pin with signal going through it. 1- 0 18- 3.07 2- 3.08. 17- """" 3- 0 16- """" 4- 0 15- """" (15-18...

I’ve done all of that, the signal going into the 43k at R5 sounds fine, what’s coming out sounds awful and low. Pulled that resistor, cleaned the contacts and put a new one in. I desoldered the op amp and the 8950, fluxed and resoldered in case of cold joints. I’m pulling my hair.

reflowed a few things and getting good input and output via the first side of the op amp, traced signal and found that once my signal gets spit out from R5 (43k) the signal is barely recognizable, just a fizzle basically of the original signal, the output of the ht8950 then just sounds like...

Yea, just might be a cold solder somewhere, going to have to reflux and reflow, hopefully that’s all it is.

Checked it out, I’m also getting good signal into the 072, but a mess coming out, going to check voltages, but I may just have a busted op amp.

After waiting months for my HT8950 to come in from Banzai in Berlin, all I had left to do was attach it to the PCB. I've checked all my connections, LED, bypass, all that stuff works great. When the effect is engaged, there isn't much definition to the sound, almost like if someone had a magic...

swapped out the jfets to remove them as a possibility, noise is still present. the only major components i haven't swapped out are the 3rd and 4th op amps. May have to set this guy aside til i get more parts in.

No, it’s just a constant sound, like hearing an airplane fly overhead while inside your house, and of course raising the gain and volume increase it, but it’s a constant. Again, even if I turn the volume all the way down on the instrument, it’s still there.

I have swapped out the 4049 and the first op amp. None of the caps are ceramic, they’re all either monolithic or film. I’m starting to suspect the jfets, as their smd and despite me being extremely careful, I may have fried one.

I may as well give it a shot at this point I have the smd j201s on the through hole adaptors.

I ordered and built 2 Obsidius boards, one works perfectly as intended, the other also works...kinda. In bypass mode its very quiet, engaged, the pots all work as well as the effect and toggles EXCEPT if i move the Grunt switch up or down, especially UP I get this loud whooshing sound even with...

I just saw this reply, but that's exactly what i did. then a little hotglue and some leads from the legs, works like a charm. Next time i just need to take my time and be more patient in order to avoid all this extra work, although it was a good lesson in troubleshooting.
