Needed a true stereo in-out chorus for a keyboard setup. This works well, with good sound, compact but sturdy design, and a good range of chorus sounds available. Have not yet tried using the TonePrint feature, but it seems like it could be useful for quick-changing presets and for designing new chorus sounds. The current library of TonePrint settings doesn't include much for keyboard players, but that will probably change over time. Some good Leslie effects and old-school Rhodes presets would be a welcome addition to the library.
