This is what’s inside a phaser. The circuit basically splits the signal in two: one signal it basically leaves alone, while the other one goes through a series of identical opamp-driven phase shift networks. On this side of the circuit, the phase is shifted in proportion to the incoming signal frequency, and when the two signals are blended back together, that swirling trippy Hendrixy sound is the slight mismatch of the phasing of the two signals.
Long story short, we have not one but TWO vintage Ross (aka Kustom) Phasers, with original box and box candy. You buy now!
