[Rwp] Stereo paning

[Snowman]

Yep, you will get comb filter effect, if you hear both wet and dry together.
Of course, make sure it is not a regenerative delay with feedback, and that 
only the wet sound is being heard.  The delays you really need here are 
measured better in hundreds of microseconds.  If you stand with a point 
source of a click sound straight off your left ear, and if you could measure 
it, you would find that the signal arrives in your right ear about one 
millisecond later than the left.  Maybe even less.   So, simulating a 
partial head turn requires an even smaller delay.
The problem I run into is that most programmable delays won't let you work 
in such small units, and the modulation is var too coarse.  But, it's an 
interesting theoretical.
