SPH-20 | Phaser Pedal


"Stun" Setting Not Included

Like many Modulation effects, Phasers split your audio into 2 matching copies. The Phaser takes those copies and smashes them back together. This smashing of signal creates notches in the output signal which means some frequencies cancel out. Have you ever criss-crossed your speaker wires, or maybe didn't plug your headphones in all the way? It's kind of like that. The notching sweeps or "shifts" back and forth through the entire frequency band present in your signal. On the SPH-20 Phaser, you can adjust the speed of that Phase Shifting using the single Speed Knob on the all-metal enclosure. The 2-way toggle switch lets you choose between a Vintage and Modern phase settings. The controls are simple, but the output is extremely versatile.

Detailed Operation

The CNZ Audio Phaser Modulation Guitar Effects Pedal provides excellent note bending and sound wave shifting effects to add warmth and depth to your music with the possibility of extreme Phaser Effects.

The toggle switch at the top allows you to switch between 2 distinct sounds with the Phaser. The Vintage option gives a 80’s vibe while the Modern option has a warm, underlying sound. With either choice, the dynamic effects from this pedal are amazing!

Adjust the speed of the Phaser modulation with the speed dial in the center. The Phaser is definitely on the slower side of modulation but can easily be quickened by turning clockwise. This effect adds some great fill to your sound. Inspire Your Music!
