DigiTech Mosaic

The Mosaic is a unique pedal that transforms the sound of a 6-string guitar into a highly convincing 12-string imitation thanks to polyphonic processing and an intelligent doubling system. With just two controls (Level and Tone), it makes it easy to achieve the famous "jangle" sound of Rickenbacker guitars, made famous by the Byrds, Tom Petty, and U2, without having to carry or tune a real 12-string. Its tracking quality is often praised, and it works equally well on chords and arpeggios. While it doesn't completely replace a real 12-string and can sometimes sound a bit artificial when pushed to its limits, it is widely considered one of the best pedals of its kind available.
