Oh snap! I haven't been on the forums much lately and almost missed this. Thanks for the shout out but more importantly, excellent work!

That is some splendid work, Clinton. Neat and clean layout and slick wiring. Nicely done!
It is super awesome that Bean shares the component libraries. Makes this kind of stuff a lot more friendly to work with.

Oh man, I love it, and it's so compact.

Clean build. You took the leap and it worked!

Yeah, I love this! Congrats! I still haven't taken the plunge on layouts other than vero.
I did manage to grab a used wah on Reverb and have started modding it to learn what's what until the Weener Wah is back in stock. It's a 1990 revision E without the input buffer. It's already got the 390r Q1 emitter resistor and the 33k in parallel with the inductor. I upped that to 47k to see if it would bring out a bit more vocal quality. It does sound good! I'd be curious what values you like where.

That's super awesome! Congrats.
I've been itching to do a layout again. I might recommend trying KiCad or another free software on your next one. EAGLE is EOL and it will be a more of a bummer to switch the more skill you get with EAGLE.

Oh man, I was just about to grab a Weener Wah having gotten ahold of an old Crybaby finally! When do you anticipate those being back in the shop?

I second the used crybaby idea. The enclosure is of much better quality than what amplified parts/antique electronics offers. I built a weener wah with one of those enclosures and I'm not that impressed with it. It feels cheap.

Wah?

Awesome! I'm glad you got this one sussed out and are enjoying it. The BF-2 has been my go to modulation since the late 90's and like you, I went through every flanger possible when I started building. Nothing could quite dethrone the mighty BF-2 until I built my HF-2. While the HF-2 isn't quite king, it's definitely sharing the flanger crown on my pedalboard.Are you using the BF-2 on guitar or bass? I really dig it on bass, it swirls mostly on the high end and lets me add more effect without loosing the groove of the song. I feel like on guitar I'd go BF-2.

A mixed update: I identified the problem but am still confused
I hooked up a guitar and amp to the PCB to make sure that it was in the problem state while I took voltages. In problem state I got a lot of weird varied voltages on IC3 (pins 2,3,6 and a little variance on 7 and 8 ) and IC4 (pins 2,4,5,6, &7). While taking the voltages I noticed that I could switch it from the problem state to functioning by probing pins 2 and 3 of IC2, respectively. Very repeatable behavior, if I probe pin 2 of IC2, I have a working pedal; If I probe pin 3, non-working. The switching between states is like a switch, meaning that after I probe the respective pin it is in that state after I remove the probe.
Anyway, I had a JRC2068 in IC1 and IC2. I switched IC2 back to a 4558 and now the pedal is working. Here are my questions:
1. WTF? Please theorize on this weird bi-modal behavior
2. Was the 2068 bad or did having one there in the first place cause this? Only difference I can see in the data sheet is that 2068 can run at higher voltages and has better S2N that 4558 (which is why I usually use them in chorus and flangers).
3. Should I keep the 2068 in IC1 or also switch it to a 4558?
