Greer Mizuki Blue Dual-JFET Overdrive - Available Wed, Oct 22nd 2025

The Mizuki Blue is a boutique dual-JFET overdrive pedal that captures the warmth, touch sensitivity, and organic breakup of classic tube amplifiers. Named after the Japanese term for “beautiful moon,” it delivers a stunning range of tones—from smooth, dynamic boost to rich, harmonically complex overdrive.

Its two cascading JFET gain stages emulate the behavior of vintage tube circuits, providing expressive response and natural compression. With just three intuitive controls, you can easily sculpt tones suitable for jazz, blues, rock, and beyond. Mizuki Blue also stacks exceptionally well with other pedals—add it before another drive for enhanced saturation, or after to boost and refine your tone.

Run it at 9V for classic warmth or at 18V for increased headroom and clarity, making it as versatile in the studio as it is on stage.

***Mizuki Blue has trim pots inside, they set the bias of the JFETs they should NOT be adjusted, as doing so will cause the pedal to cease working or function improperly. You have been warned.
