   Ok - phasers once more.

   I am even thinking about an all CMOS phaser solution. Don Tillman
   showed us how to use a 4069 as a hex VC resistor, and built a
   phaser from that and some opamps.

Yep.  Though someone else pointed out that an Electro Harmonix product
might have done this independently.

   But what if we want to replace the opamps with 4069's, too? 

Note that 4069 FETs are noisey when used as linear amplifiers.
(When they're voltage controlled resistors it's not a problem.)
