What makes the Electro-Harmonix EH-7100 Polyphase unique compared to other phaser pedals?

The Electro-Harmonix EH-7100 Polyphase is known for its vintage 1970s design, offering a distinctive sound character with rich, swirling phase effects that are ideal for classic rock and psychedelic music styles.

Does the Electro-Harmonix EH-7100 Polyphase have a true bypass feature?

The original Electro-Harmonix EH-7100 Polyphase does not feature true bypass, which is common for pedals from the 1970s era, so some signal coloration may occur when the pedal is not engaged.
