Hi all,

This is one of my first vero attempts but currently I'm unable to find my issue.

I've tried to build a Fulltone OCD V3 clone following this schema :

However while activating the effect the sound drops.
If I crank my amp at some point I hear that a very faint signal is coming though.. Clean however. But I need to get is past 8 on the volume and sit next to the amp.

I check the components and cuts of the vero but was unable to find anything.

The Ic has the following voltages :
1. 7.50 8. 9
2. 5.50 7. 7.63
3. 4.19 6. 0.46
4. 0 5. 9.32

For what I have foudn so far I understood that pin 3,4 and 8 are ok.
pin 1,2,4 and 7 are to high and 6 is low.

However no idea how to proceed from here.

Anyone some tips?

Thanks in advance.

Br, Hugo

You seem to be missing two of the cuts on the underside?

Well.. that was not the only problem.
After adding the cuts the IC was of course fried. After replacing I still had no response what so ever.
Build a sound probe to see if that would help and yes.. the circuit itself was working correctly.

All issue were solved after removing the stomp switch. So something is wrong there.
Need to have to wait till I receive some new ones as I'm out of stock but consider the issue solved ;)
