Thanks Dirk. :wink:

Duke, could you please just check the value of the Depth pot. I guess from the partial marking and code bellow that is A but I don't know the value. Thanks and sorry for bothering. :thumbsup

Here is the small switching-ps board. There are couple of uncertain things.
1. traces under the small switch are not visible so I'm not 100% sure that all connections are redrawn correctly.
2. Diode near the power jacks - markings tell nothing,, could be 1N4XXX or even zener diode 9-15V????

Solve this and we have a fine finished project. :thumbsup
Cheers to all.

I bought this for pennies. Boss CE-2 is the MN3001 and MN3007. What do you think is the meaning of these modify it to better IC's?

Certainly in his will True Bypass.

I had huge fun reading this thread.

I also have some Koda units I bought them used for 10 to 15 euros.

Are you guys really cloning a 15euros pedal? lololol
Theres nothing wrong in being cheap, it can be a great circuit and sound good, but really theres a lot of those pedals for sale for the price of 1 hammond box and 1 3pdt switch, so why not just buy the real thing?
