Help with circuit identification (Hello again!)

[MikeH]

Hi folks!

I have taken a rather long hiatus from DIY pedals (mostly because I've been focusing my time and efforts in the realm of professional luthiery) but I have some free time these days and I'm getting the itch again (for building pedals, that is).

First things first, I've been digging out old projects that I never was able to complete (or successfully debug). This first one looks promising; some sort of tube based OD. I thought tube driver at first but that's not it. I'd like to get it working, but I need to know what it is before I can do that. Can anyone here recognize it by the layout? I've checked at ggg and tonepad but nothing looks right. Thanks!

Zen Drive II?

Nope, can't be. Sorry.

I HAVE been away from this a while. I realized (duh) it's probably printed on the trace side of the pub. I popped it off and [drumroll] it's a shakka tube.

Which is hilarious because I have ZERO recollection of building that pedal. But I did have a bit of a problem for a while...
