Paul's idea for a pitch extractor is a good one.  A few more ideas:

- Nonlinear circuits.  Serge Tcherepnin came up with some good ones;
according to him, he was inspired partly by fuzz boxes, partly by the
Buchla stuff.  These can be really simple, but are really cool.
- Nonlinear filters.  Check out the latest Computer Music Journal for
details.
- VC phaser.  Maybe a cheap design, using the 4069 as 6
voltage-controlled resistors, and 6 op amp phase shift stages, plus
input and output buffers.
- Frequency shifter.  OK, there is no way to make this cheap.
- Resonators.  Check my page (http://www.seanet.com/~costello) for a
good design.  Maybe replace Vactrols with your own photocell-LED
combinations.

Otherwise, you've got things pretty much covered, as far as I can see.
Having lots of filters is very nice.  Man, I need to get that diode
ladder working! (Curse these clumsy hands!)
