The vintage sound of an analog OTA-based phaser melded with contemporary parameters out the wazoo. From classic and not-so-classic sounds, subtle and over-the-top phase tones, mellow through seasick pitch vibrato, ringmod, glitchy octave effects, and outright strange phased/autowah/tremolo-like hybrid sounds you won’t find anywhere else. There is no doubt that the Whetstone Analog Phaser can do things that your current phaser can’t.
The manual below has a great breakdown of the switch/knob layout and gives some clues to the interplay between them.
