this is a John Hollis circuit - with Mark Hammer MODS to keep oscillator cycling noise out, to blend wet and dry signals, and includes a  Psuedo ring modulator that can be switched in. It is a chorus that does what it is supposed to do. . . ,it uses an analog bucket brigade delay chip, and the effect dosen't go terribly deep, but it sounds great. . .and the ring mod settings are pretty wacky. . . . . . . . so there..
LOW END-ish CLIP: What else would you expect to hear? (sorry guys. . . . ) one sample, through a few different settings.

Ring Zomb-ulator: yup. thats what it is.
