The DigiTech Mosaic is a 12-string effect pedal designed to add a lush, shimmering chordal texture to both acoustic and electric instruments. It features a true bypass design to ensure your original tone remains unaffected when the effect is off. For optimal performance, the Mosaic should be placed first in your effects chain.
Device Overview
The pedal features two main controls:

- LEVEL: Blends the amount of the 12-string effect into your dry signal.
