Yeah, I'm banging my head a little bit - I tried replacing R43 (15K) and same result on the output voltage there. Not seeing any obvious shorts either but it's got to be something around there, right?

OK! Finally had time to get back to this tonight. @Dan M my readings are completely off from yours which makes me thing something is wrong with my power section and maybe not the LM13700s ... 1 0.65 2 0.85 3 0.85 4 0.75 5 0 6 0 7 0 8 0.2 9 0.3 10 0.15 11 8.8 12 0.15 13 0.85 14 0.85 15 0.15 16 0.08

Yeah, I feel the same about the Peachtree boost. I wonder if there's a way to switch out an R value to at least give it more volume?

Just finished my first hydra build and wow, how awesome does it sound (full build report coming later). It has me thinking, has anyone tried to build an 8 head hydra? Not sure how useful it would be but maybe you could do a stereo one? Is it possible to sync multiple fv-1 clocks with one of the...

Wow, well this pedal was quite a journey. At first, I got the initial PCB with the mounted rotary switch and that seemed to not work at all (something weird with the power line?) - anyway @PedalPCB was kind enough to send me a fixed/updated PCB with the rotary board. It went together well but...

Request for the schematic for the headphone amp?

Update to the update. IT WORKS. Turns out similar to @Dan0h I had some bad joints on the headers that were connecting the rotary to the board so when it was in the case it was pressing on them and knocking them loose. Reflowed them all and cleaned the board thoroughly and ohhhh yeaaaaah. Going...

Quick update! Been super busy with actual job so didn’t have much time last week but I ordered some 4017 from mouser and once they arrived, swapped it in and boom! Harmonies! Then I finally tried to box it up yesterday and (sad trombone) loud squelch! Checked my grounds, looked fine, so now I’m...

Actually (still up and tinkering even though I have to be up at 5 …) I tried referencing the madbean docs which have the voltage readouts and mine are wildly different. Anyone have a working one they don’t mind probing and posting the voltages for IC1 at least?

looks awesome! Tubes kind of scare me but this seems doable.

OK! An update on this as I've done a bit more digging. I replaced the TL072CP with an IP -> no change. I tried a bunch of different CD4017's with no change. Then I realized I have a working captain bit pedal that relies on the CD4024BE. I swapped the one on the flock with a working one from the...

Tried to breadboard the test circuit but the only issue is that I don't have a working IC to test with to know if my circuit works or its just the IC. I think I'll order some from mouser and come back to this when they eventually arrive.

Haw man, that would suck. I thought jameco was supposed to be reliable.

Damn, I seem to be struggling lately! Trying not to get too discouraged since I did complete some other working things recently that I have yet to post (Hydra, Syncrohwah). My AionFX Redshift build is not working as in there is no sound when engaged. LEDs light up, secondary switch switches...

Yeah for me at least from the printing on the chips mine are all "BE", too. Could it be the TL072? I have a CP in mine not an IP but I thought those were functionally the same?

This was my thought too - anyone have any idea of the exact correct ICs that worked for them in this build? Maybe even with sources? I see Jameco has most of these but variations of them. I bought some from mouser and some from stompboxparts.

Ok! So I had posted that my flock fuzz was working but after watching some demos of the swarm and messing around for a bit it seems like it’s not actually working as it’s supposed to. Here’s a video: Basically, the fuzz part is clearly working but the octave knobs either hold a single not or...

Ok! So thanks to @PedalPCB for the new board - I rebuilt it this weekend and finished it up today. At first it had the same problem but realized that there was a bad joint right at the beginning of the circuit that once fixed WHAMMO, the crazy noises commenced. Now to case it up and figure out...

I hate to admit how many times now I've soldered the breakoutboard/3pdt switch upside down!

OK! Thanks for the schematic @PedalPCB. I traced around and it seems like the issue might be with the second stage of the op-amp? The first stage is loud and clear, the second stage has a huge drop in volume which may make sense why there's no signal going through the PLL section. I tried...
