Yesterday Effects Unit Shifter Four-in-One Analog FX Pedal

U.K First

The Yesterday Effects Unit Shifter is a meticulous copy of the original Stereo Polychorus, designed to mirror the circuit and control layout exactly. Every knob movement on the original is matched here, no reinterpretation, no simplification.

Built using the same IC and bucket brigade device (BBD) chips found in the vintage circuit, Unit Shifter captures the unmistakable depth, motion and character that made the Stereo Polychorus such a defining modulation effect.

From subtle widening to jet like flanging and experimental comb filter textures, the Unit Shifter delivers the immersive stereo modulation that has shaped countless records.

The Polychorus circuit has a reputation for creating generation defining, time withstanding sounds. The Unit Shifter continues that legacy - faithful, powerful and unmistakably alive.
