The TC Helicon VoiceTone Harmony G-XT builds on the massively popular VoiceTone Harmony-G with a full suite of automatic vocal harmonizing tools. Specifically designed with singing guitarists in mind, the Harmony G-XT automatically produces rich and sophisticated harmony parts based around the input of your voice, guitar, or both. It generates two distinct harmony voices, each of which is tweakable via EQ, onboard effects, and a myriad of other voice-shaping options. If you're a performer looking to expand your sound with harmonies at the flick of a switch, the VoiceTone series from TC Helicon should be at the top of your wish list.
