Drafted schematics of Devi Ever - Ruby, 90 and Hounds Tooth circuits using this old snippet from the Devi forums and following along with the written descriptions. That last line adds some confusion about the accuracy of this info.

Redrawn schematics. These haven't been verified in comparison to a traced pedal.

probably want to flip the 2n2907A as it is a PNP device. Pretty cool little octave/wavefolder block.

My hounds tooth trace. it actually says 05+DB+ on the inside which i find funny.

Are you saying that the transistors are attached Collector to Collector, Base to Base, and Emitter to Emitter?

I would assume the PNP would be connected Emitter to NPN collector. But, I wouldn't want to assume.

Connected Emitter to Collector should give a crude octave/wavefolder effect. And sound gated.

The schematics in this thread correspond to the DE circuit building blocks that she has used for quite awhile. Not to say there's anything "wrong" with trying out a different transistor orientation, of course :thumbsup

Devi circuit is the best practice to do if you want simple 1590A build. Did in perf, easy.

...and this is exactly what it does! if you combine it with an extreme hi-end cut (see the Hyperion or SM) you can wind up with more of a pure octave.
