Comet Filter

I ran into Masaru Kubota's circuit snippets and they look pretty interesting. Info about this one: The Comet Filter is a Twin-T notch filter that I modified.  That should clear up any confusion...  I modified the Twin-T notch filter around 1995 so that I would get a sound that sounded like a phase shifter.  If you're in love with this circuit, then I'm flattered.  The sound ranges from low-pass filter to scooped metal to hard rock to cardboard.  If you use an SPDT, not a DPDT, bypass switch, that disables the output, with the input still connected to the input of this circuit, the circuit still works.  You might even say that the circuit works better than when the filter is directly in the signal path.  This circuit sounds really good and even better, it can keep you out of the "poorhouse".  By the way, the comet that this filter is named after is the Comet Hyakutake.
