Hey guys, I'm wanting to build a filter pedal, but I don't know what kind I'm looking for.

What I want is one that can make the effect heard on the opening riff of "E.T.I." by Blue Oyster Cult.  It sounds like an envelope filter, but sort of makes an "ow" sound instead of a "wah" sound.

Any ideas what pedal that may have been?  Any suggestions on what clone I can build that will get that same sort of sound?

Thanks in advance!
