thanks for replying, john! :)

i 'd better get a mixer module, then.

i will check and post extensive information asap.
i discovered this behaviour by accidently shorting ring and tip from
a patchcord plugged into the 820's 'audio in' with my fingers.

no inputs at all, just the 420 oscillating near trip point.
i noticed just slightly delayed reaction from the freq and q pots
too, btw, which makes it annoying to set the trip point at an exact
position around self-oscillation.
perhaps this happens when the module is still 'warming up'. i'll
check for that too.
