Quality sounds and construction
I wanted a chorus pedal but chose this because it not only has great chorus ability but also offers flanger and vibrato. John Petrucci has designed two versions of each effect, and these are immediately useful. In addition there is a TonePrint position which can be filled with the downloaded set-up of your choice, or edited yourself on PC or smartphone. This works really well and creates infinite versatility. It has no noise, allows the tone of the guitar through and is well built. An excellent pedal.
