Schumann Two Face fuzz.

Well, thanks to jerms over at the DAM forum, I finally got to trace the Two Face. I'll tell you right now.... not for the faint of heart. The amount of el cheapo wire that's stuffed into the enclosure is hallucinatory. Take a look.....

I also had a request for a close up of the knobs, so here are some more shots, including the fuzz, and clean board. The 12vac to +/-12vdc board is identical to the PLL, or Lion.

And of course, my trace,

Going to breadboard this in the coming weeks to validate the trace. I've been playing with this over the past few days, and it's a little reminiscent of the Skyripper, but more menacing. It's noisy, buzzy, with lots of Velcro stuff going on. Has settings for oscillation induced screaming, and much of it is interactive with the guitar's volume. Just a plain weird-ass box.

I love it. :p :icon_mrgreen:

I'll will try (I mean try) to put together a video of this unit in action. I'm not really happy with the videos out there now, since they don't show the guitar volume interactivity, which is important. It just so retarded though, I don't know where I'll start. :whateva:

EDIT: I've added the power pin numbers to the LF351 in the schematic. I forgot before, sorry.

That looks more chaotic inside than my builds. Just crazy! How long did it take you to trace that? You must have zen like patience.

Makes me lol every time. If someone were to do this now, they would be torn apart on stompbox forums.
The wiring is kinda like the Teisco policy of "there's a ton of shit going on in here, so close it up and let's hope it works".

Well done, dude.

Zen? No young grasshopper, I have gone beyond Zen. I have a daughter in the 20's, and three teenagers under my roof.

Now, try to snatch the grain of rice from my hand.

:p

Oh yeah.... about three days.

I wonder if this was to deter people,from cloning. Ancient booby trap.

Definitely as I recall. I think that's the same one I owned. Intensive work by you to be sure, kudos.

I don't even know how the Schumann dude could manage to build something that messy and it still somehow works :idk:

Yeah I know. Kind of boggles mind. Though strange things do happen in this world. How's that soldering? I soldered better than that when I was 10 years old. I suppose as long as it works it's ok.
