TC-Helicon VoiceTone H1

Worth the money. I like it very much, it is very simple and if you take the time to carefully read the instructions and to experiment a little bit, you can get some realistic harmonies.

This stomp supports harmonies a third or a fifth above or below: you can set the key manually, or use a guitar or keyboard plugged int to detect the key. This works with keyboards or guitars but you need to be playing chords for the box to correctly detect your key.

The basic operation is very simple to learn, the instructions include a key and scale chart to help you to dial the harmonies in because some minor and major keys require tweaking.

The Dry/Wet knob determines how prominent the harmonies are. The drier, the more emphasized the lead vocalist is. The wetter, the more emphasized the harmonies are. Be careful...anything over twelve o'clock on the knob setting starts sounding unnatural. The best place to stay is around nine o'clock and increase it slowly until you find the sound you like.
