This is the rare, no longer manufactured TC-Helicon VoiceTone Correct-XT. Everything works great. Some marks and scratches from use but still in very good condition. Does not come with the power supply cable. The reason this unit is as popular as it is, is the super simple vocal processing, pitch correction, EQ, and the anti feedback. I use one of these for small venues where a microphone picks up the speaker sound creating a feedback loop. This unit takes care of it by identifying the bands causing the feedback and eliminating them. The auto eq is also super simple to use. Please look at my feedback and buy with confidence. ---------- TC-Helicon VoiceTone Correct combines pitch correction with tone and dynamic shaping that put a recorded gloss on live singing.
