The richer the harmonic content of the sound, the more there is to filter and sweep. Try adding distortion using the SansAmp PSA-1 before the phaser–it’s a cool variation on the common signal path used when putting a phaser in front of a guitar amp.
Dr. Moog apparently took these mantras of early 21st Century recording science to heart when he designed the Rate knob on his phaser. Flick the Rate switch to Hi and let the party begin. Try muting a track and mixing in bits of extremely phase-swept material.
All the controls on the Moogerfooger 12-Stage Phaser are fully independent of one another. This means you can set them in any combination that you wish. There is no such thing as a “wrong” combination of settings, so you can experiment all you like to find new, exciting effects for your music.
