4013 build suggestions?

[El Heisenberg]

I have one 4013 left from my MXR bluebox. I'm thinkin of making anoter one, but what else could I build with just one of thesE?

thanks

Boss (Chopped) OC-2.  A cleaner sounding octave down.

I liked the two octaves down with the blue box. But ill try this.

Is the a sub FET i can use for the 2SK30?? Also why a TL074 and an LM324? Why not two of one or other??

Or simply save it for a flanger at a later date.

I used two TL072's and a 324.  I'm not sure why they use the 324 instead of a cleaner quad op amp.  Also I used a 5952 for the jfet and a 3904 for the bi-polar.

I used J201 for the fets and tried a tl074 instead of the 324. There was no difference, so I guess there is no problem to use a tl074 or 2 tl072's instead of that 324...

I would need more ICs for the seconds octave down wouldn't I?

I think it's possible to make an oscillator from a 4013.
