Really sharp looking.

I bought a 12v power supply and removed the charge pump and diodes and all is right with the world. This resolved all of the issues and sounds amazing.

Nice and clean.

So awesome. Nice match up.

Same box or same board? If you just want two circuits in the same box, take the out on the first stomp to the in on the second stomp.

Ooh very nice. Elegant looking.

one quick tip to share I learned recently -- best way to open a through hole on a board is heating the solder and then putting a toothpick into the hole and let it cool.

That is brilliant. I think this tip alone could have saved me countless hours of troubleshooting issues.

Ahhh nice. I'd be using an earring with a post, but I be this wouldn't wreak havoc on a PCB.

There is a great vero layout for a small LPB1. Google is your friend here. There used to be a smd layout somewhere. You may have to google it.

Hey man, I really appreciate your help.

Hmm... A battery will also use the charge pump so maybe it's not heterodyning... Are you using a switching wall wart like a One Spot? Some of those switching supplies are noisy. Try finding a linear wall wart supply to power it, one that has an actual step down transformer in it.

Yeah, I looked up heterodyning sounds, definitely power supply noise. I use a Dunlop power brick most of the time. I've tried 2 boss power supplies and a boss wall wart. Now, I live in an apartment, do you think that has anything to do with it? How can I calibrate it with a frequency counter? I have a decent DMM I can use.

What kind of noise? Hetrodyning from the BBD clock and charge pump? If so, try putting a 30-50pf cap between pin 7 of the charge pump and ground. This will lower the frequency of the charge pump... Ideally, you want the CP to be at 17-20 kHz. If you have a frequency counter you can get the CP working frequency from pin 2 of CP

Maybe so, it's dead quiet with a battery.

If I were to get a 12v power supply, would I need to make any modifications or just keep it at the 9v config? Same noise everyone else seems to have. I have it at a minimum after working it for two days, it's usable now with just a little noise and that classic flanger swoosh. I"m thinking a noise gate will get rid of that little bit.
