TC HELICON VoiceTone C1 This item is the TC HELICON VoiceTone C1. It was purchased from Soundhouse. You can intuitively control a wide range of effects, from natural pitch correction to harsh, hyper-pop-style autotune. It has scratches from heavy use, but it was working fine until recently. The main unit and a new Classic Pro adapter are included. This adapter works without any problems. If you would like the original box, it will be an additional 500 yen, so please comment if you want it. Please check the condition before purchasing. No price reduction is possible.
