other than the constant sine wave ringing over the note, pretty incredible. got some shielded wire in the mail. hoping that solves the issue

would that make it less slap-backy at with Dim turned all the way down?

i haven't boxed mine yet. currently testing and yeah, crazy oscillation with the gain up. 2 gates to take care of it. touching the top of the bass pot seems to quiet it down. touching the mid and treble pots make it worse. i've reflowed them all to make sure i don't have a bad ground or...

got it sorted. i was right. that 1k resistor was eating up all the power. error in the layout. all good now. thanks for looking. saving this for posterity

Did some measuring. Only getting 1.5v at pin 8. Seems to be getting robbed by that 1k resistor right after the protection diode. I found this schematic, which I’m sure isn’t quite official, but might point to the problem. Right here in that same spot there’s a resistor just labeled “1”. Not 1k...

working from this layout, which i know is unverified and has no support in the comments. built it, checked it a hundred times, i'm confident that my build is solid, but the layout might be an issue. used 5532 op amps. got no output signal. with an audio probe i was getting signal at pin 3 and...

Very interested to see if anyone knows what adjustments one would make to eliminate some noise. This thing is NOISY

simplified it significantly and followed the diagram you drew. put the resistor on a switch so i could A/B and also have 2 modes. and seemingly all it's doing is cutting the repeats short and not actually changing the frequency response at all

so i finally understand part of what my issue was. i was trying to add this to the mix control, not the end of the repeats. pin 3 of the repeat pot is going to a 33n, then a 5.1k, then to pin 1 of a 10k pot. pin 2 to ground. pin 3 to the repeat return (formerly pin 3) on the board. annnnnnd...

I’ve only ever biased J201’s before, and I was just instructed to get them as close to 4.5v as possible. Do I bias 5457’s the same way? edit: just remembered that this pedal runs on 15v with a charge pump. so should they be 7.5v?

in the gravitation reverb it cuts bass. or rather that's the sound we hear. very well could be adding it. I'm just throwing mud at a wall at this point because I've tried a couple things and none have worked and this thread went unanswered. if I go from the pad that should be pin 3 of the mix...

could i add this section from the gravitation to a seabed before the mix control?

found a tiny shred of wire that was bridging to ground. then i was getting the high pitched squeal some users have mentioned. switched BACK to the 1054 charge pump that i swapped when i thought maybe it was the problem. squeal gone. everything seems to be running normally now

Bump: please advise

my ground issue is entirely fixed, awesome. my LED is changing when it gets signal, but i'm not getting much output. if i CRANK the volume on the distortion pedal, i get the faintest glimmer of a signal. also odd, i'm certain i tested this LED and know it to be blue and red, but i'm not getting...

i was wondering what that other pad was for. I'll give it a shot and report back. thanks!

ground loop stops when i hold both cables for the key/thru. is there supposed to be a ground between them? because it isn't shown on the wiring guide. very little signal is getting through. LED stays blue no matter what. guitar into key > key out to dist pedal in > dist pedal out to gate input...

hoping to get a bass rolloff knob to the delay'd signal. it's just so murky, and i'd like to be able to dial that out a bit. other schematics have a passive filter either before or after the mix control. the cataclysm delay has a BMP style tone stack, and that's too much. electric canary's...

just threw the LPF that is made by R17 and C8 into the calculator. with the WRONG cap in there it's about 480hz. i was right about what was wrong with a problem i caused 🙃😂

wait. WAIT A MINUTE. yep. i'll be dipped. i must've grabbed one too many out of the bin and just filled in the blank. that'll teach me to work slower. tested. it's perfect. there's a SLIGHT (and i mean F'n SLIGHT) volume change when it's engaged, but per my understanding that plagued the CE-2...
