I am currently reviewing this project and have incorporated a lot of the mods mentioned. I have also completely redesigned the printed circuit board layout and it is presently being fabricated - spare boards will be available - PM me for details if interested. I am also working on redrawing the new schematic, but this may take a few days to appear. in the meantime, here are some pictures of how the new board is looking.
cheers

I can sell you one of my pcb, but at this stage it is unverified to work until i have actually built and troubleshooted it. If you want to give it a go unverified, then PM me for further details.

Great rotary. I liked it for guitar better than in my CX3 though.
Edit... I said that 5+ yrs ago already

Hi everyone
this is my way of seeing the bajaman layout but it does not work. could someone give me a hand to make it work? I used is a mn3007 and powered at 12vac, what should I replace to make it work? I repeat I followed the layout of bajaman a page 1. Please help me

We do not know. There is no fixed recipe for what to replace. Start of by check if all DC supply voltages are available.

......also use a 16vAC adaptor NOT 12vAC

I have a question to CX-3 users/builders. I've finished one recently, with MN3007 instead of the MN3004. It works, but I'm not sure about one thing.. It's noticeable only on fast setting - modulation effect speeds up, slows down.. but there's this one brief moment like it was going to stop.. it's hard to explain.
Here's the sample.
https://www.dropbox.com/s/q59u9mzoj5j6thw/cx3.mp3 (alternative link, to wav format
https://www.dropbox.com/s/fhcjomrezboxeqk/cx3.wav)
Slow setting first, then fast.
