AW: Phasers - if you don't have enough already

I have the schemos. So this "E" device is actually a 4049 ?

The modulation waveform smoothing of LDRs was already mentioned.
Distortion character is another important point. I have a very cheap
phaser (don't remember the name, but it's the same which Maplin
sell, only that Maplin is much more expensive) that uses FETs. Very
noisy, but unbeaten as an extra distortion device for my Korg CX-3
organ. My 13700-based phaser has a rather ugly distortion when
the input level is too high, especially in stereo mode when one channel
is clean and the other one is distorted. My "Neptune" Phaser (opto)
has a very nice sound, but I am a little disapointed by its distortion
at overdrive. The ARP ladder is embedded into a compander system
(with CD4007 as VC resistors !), and this shows the best behaviour for 
overdrive. This might have to do with the resonance. If resonance breaks
into oscillation on a phaser, it sounds much worse than with a LPF filter, 
for example. With the whole phaser inside a compander, it won't 
"scream" at high reso settings, but has a very strong resonance effect 
nevertheless.
