DigiTech Mosaic

Mosaic makes a six-string sound like a twelve. It is a polyphonic effect, so it holds up under a full strum rather than only tracking single notes, and it adds the octave-paired shimmer and movement a twelve-string gets from its courses without the tuning and the neck that come with one.

Two controls shape it. Level sets how much of the twelve-string effect sits in the sound, from a hint of thickening to the full chime. Tone adjusts the high-frequency enhancement applied to the effect signal - clockwise for brightness. The pedal is true bypass and runs from a 9 VDC supply.
