Description

The NostalgiTone Phaser Single brings the essence of several iconic designs into one compact circuit. Using LDRs (Light Dependent Resistors), it creates smooth transitions between phase shifts, resulting in an organic modulation tone. With precise control over Rate, Intensity, Volume, and Voice, this Phaser allows you to fine-tune your sound for maximum versatility. Reduced noise levels ensure a clean audio experience, while placing it pre-distortion in your signal chain delivers classic phasing tones that perfectly complement other effects.

• Easy Wiring: No more daunting wiring hassles! Say hello to beauty under the hood. Enjoy all-analog tones with modern features that will slip into your gig bag, ensuring you are always ready to unleash your musical magic.
