Yes you can, but watch out for the phase of the unit you put in. If it inverts
the signal (a lot of pedals do) all HELL CAN BREAK LOOSE. Units that have
changing phase like a shifter may do wierd things (maybe wierd good, maybe
wierd bad. I tried tapping different filter stages in a PRO1 and the 1st and
3rd stages did naughty things (not "good" naughty). If you use a filter like
the CEM3320 (in 4 pole lowpass) the feedback goes from stage 4 output to the
input, so it would be easy to F*ck around with items in the feedback path
(unlike the more complicated MS-20 feedback arrangement that Paul was warning
about.  ;-) Harry

Would it be possible to implement a in/out connection for a filters
resonance feedback loop? Might be cool to patch a phase shifter,
or pitch shifter or something, or even another filter or ring modulator
in this loop.... crazy unpredictable sounds i'm thinking of now. (i hope)
