Implemented Fulltone OCD (schematic included)

[sixtystring]

This pedal is pretty much instant "God Tier" tone for me...

I know its been asked for a few times throughout the years, but I don't think a schematic was ever provided. My understanding of schematics is pretty basic, so I've attached two that I found for reference.

Which version is this? I have a semi-recent one which is almost indistinguishable from the Danelectro Timmy knock-off.

I believe the top is a v1.4. The bottom one says "rev 4" at the top, but seems to only include notes about the differences for v1.1 - v1.3.

This page (https://revolutiondeux.blogspot.com/2008/07/fullclone-vlod-fulltone-ocd-by.html) includes a PDF download (http://www.box.com/s/5ef844ca1fbe0571d91d) which highlights the differences between some of the versions.

That dude also has his own schematic for what he calls the "Super OCD" which adds more controls.

+1. I have a custom made dual drive/boost with one side being a v1.3 OCD circuit. Pulled it out today running it through the Vibrolux model in the Axe and it is pretty glorious. Could get close tweaking the Timothy 2 model but the more the merrier when it comes to these things.

+1 to the OCD. I thought it sounded better pushing my JCM800 2203 than the 2203 with equivalent gain haha.

For one of my bands, I still use an OCD in front of a Mark V 25 set clean and it sounds awesome...I actually prefer it to the distortion channels on the amp. They also pair ridiculously well with AC30s.

I have the OCD 1.1 and the 1.4. Love the 1.1 and like the 1.4 but could live without it, although I'm currently stacking the 1.1 in to the 1.4 into the Axe and it sounds pretty f'n good.

If I could have my OCD wish it would be for 1.1 in two versions: HP setting & LP setting (IIRC changes something about the treble shelf). The 1.4 is nice (and I would like it as well), but it sounds a little more generic.

Version 1.1 (PCB layouts but I think schematic could be derived):

Looks like v1.4(?) LP mode has been implemented but not confirmed exactly.

Cliff plans to do the HP mode as well.

LP mode implemented but awaiting HP mode:

It's modeled in the LP position. I'm going to add a model of the HP position.

I'm so stupid!
I still can't decide which one is "OCD"? "Fulltone OCD"
Thanks for help.

CDO - so the letters are in proper alphabetical order....

HP mode implemented in 13.02. Sounds delicious!

Added “Compulsion Distortion HP” Drive type. Existing type name changed to “Compulsion Distortion LP”.
