The Mojo Hand FX Nebula IV is an all-analog four stage phaser pedal overflowing with funky vintage tones. With a bit more control than the "standard" phasers, you can easily dial in the sweet spot for your sound. The Nebula IV, like all of Mojo Hand's products, uses top shelf components and craftsmanship, true bypass switching, and is built to last for a lifetime of touring and studio work.
