OCD anyone built it

[Kipper4]

Has anyone made a OCD clone?
Which schematic did you use?
I'd like to have a go. I have some BS170 trannys and TLo72 op amps

Looking for a verified schematic or layout please.

These are verified:

I've built a few, some on vero and one or two from Madbean's Egodriver project. They all came out pretty close to the real thing tone-wise, but a bit harsher. I opened up a real one and the only significant difference I could see in the circuit was that most of the caps were multilayer ceramics, not film.

Versions 1 through 3 don't use the 1n34a, and only early runs of version 4 seem to have had it. The version 4 I opened up didn't have one. The pot values weren't the same as what a lot of the DIY schematics call for either, but I don't remember the actual values.

I made my OCD from the board shown, and it works great. He has got other great projects here also.

Works very well indeed.

In the end i went with the IvIark Fulltone OCD V3 Worked from the vero layout (its my first time im a vero layout virgin)
Seeing as how everyone who built version 1 didnt like it so much.
When i get the remainder of the parts (waiting on 2x 220nf caps)
My builds are getting tighter everytime. I might have to get some vero next time instead of doing everything point to point.
What size of protoboards do you guys normally order please?

With you also being in the UK, I buy the large 119mm x 455mm board from here:

You can make lots of effects with just one of those, this shows how big they are:

Thanks IvIark

Did you notice i made your version 3 of the ocd from your layout. Good work mate.
I hope to do the same for others in the future. Thanks for sharing

[IvIark]

Yes, I saw, have you finished it or are you still missing a couple of parts?

[Kipper4]

I'm waiting for 220nf caps from thailand mate

[IvIark]
