in the "64er" magazine there was a small circuit like this... basically a 
modified double-t-pole filter. i've used that a while, sounds "interisting" 
atleast :=) now i am using a cheap "pseudo stereo" IC (something that is 
typically used in cheap ghettoblasters etc for "super stereo") which works 
_very_ well...adds a quite cool "drive" to chipmusic and is not as obvious as 
the t-pole filter (the filter puts high frequencies to left and low 
frequencies to right, whereas the IC fiddles with frequency-depended 
phase-shift resulting in a "whidened" stereo signal with even distribuition 
of frequencies.)
