You were smarter than me! At some point in that era I got an Arion Stereo Flanger because a) everyone else had a chorus, who wants to be like everyone else? and b) stereo, baby! I don't know what I thought was going to happen with that. (Narrator: nothing ever happened with that.) However, that pedal can self-oscillate, which I confess I have used.I have the Studio Series flanger and it is my favorite flanger!
I know it just said "Distortion" on it. I would guess Boss or something fairly generic along those lines.
