Madbean CE2 Clone de-bug

[the3secondrule]

Just finished my CE2 clone using Madbeans Porkbarrel PCB. I'm getting signal on bypass, and when the pedal is engaged im getting clean signal, no chorus.  when I flick the vibe switch, I lose all signal (which makes sense as it kills the clean signal, and thats all I have at the moment).

can anyone post voltages for me to check mine against?

Also, I bought my mn3007/3101 off ebay. the seller had good feedback, but now im pretty worried they are fake.

any ideas where I should start to debug? is a fake BBD the most likely answer here?

Cheers,

Jeremy

This has been the fix for some people:

thanks James, Tried that, no Joy.

seems like my problem is around q4, but I can't see for the life of me what it is...

Any luck on this? I'm having the same problem - lifted pin 8 and I'm getting signal now, but no effect. Neither pots nor toggles do anything, with exception of the trim, which does affect the level. Bizarro.

[the3secondrule]

Yeah, turned out I had a dead mn3007.

Swapped in a new one and it worked straight away

[gmiddleb]

Yeah, I just saw your post on madbean's site. Weird though - I got my 3007 (and 3101) from Smallbear; figured it would be okay. I'm gonna have to just post voltages and go from there...
Thanks.
