the 490's a pretty nice filter - nice and liquidy in the upper 
resonance ranges.

but... in my experience it overdrives *super* easily, and pretty much 
stops behaving like a filter - the resonance control does very little 
and tweaking the filter knob gets kinda flanging effects.

i have to attenuate the output of my Oakley VCO a *lot* to get 
regular filtering behaviour out of my (borrowed) 490. if any filter 
needed input level knobs, and of course this doesn't have one :-)

is this normal behaviour? thanks....
